More than one Bootstrap Carousel with shortcode?

I have created a custom post type for my Bootstrap theme to create a Bootstrap Carousel and shortcode to place a carousel on a page.

Problem is I would like to have multiple carousels on my site but can only create 1 with my code.

How do I modify code to be able to create multiple carousels and place with shortcode like [carousel id=”xx”]?

Here is my code :

function jd_bs_theme_setup() {
      add_image_size( 'jd_bs_carousel_image', 1170, 385, true);
  }
  add_action( 'after_setup_theme', 'jd_bs_theme_setup' );

  // Creates Carousel Image Custom Post Type
      add_action( 'init', 'register_jd_bs_carousel_image' );
      function register_jd_bs_carousel_image() {
      $labels = array(
      'name' => _x( 'Carousel Images - use shortcode[carousel] to insert into page or post', 'carousel_image' ),
      'singular_name' => _x( 'Carousel Image', 'carousel_image' ),
      'add_new' => _x( 'Add New', 'carousel_image' ),
      'add_new_item' => _x( 'Add New Carousel Image', 'carousel_image' ),
      'edit_item' => _x( 'Edit Carousel Image', 'carousel_image' ),
      'new_item' => _x( 'New Carousel Image', 'carousel_image' ),
      'view_item' => _x( 'View Carousel Image', 'carousel_image' ),
      'search_items' => _x( 'Search Carousel Images', 'carousel_image' ),
      'not_found' => _x( 'No carousel images found', 'carousel_image' ),
      'not_found_in_trash' => _x( 'No carousel images found in Trash', 'carousel_image' ),
      'parent_item_colon' => _x( 'Parent Carousel Image:', 'carousel_image' ),
      'menu_name' => _x( 'Carousel Images', 'carousel_image' ),
      );
      $args = array(
      'labels' => $labels,
      'hierarchical' => false,
      'description' => 'Images for Bootsrap Carousel',
      'supports' => array( 'title','thumbnail','excerpt' ),
      'taxonomies' => array( 'category' ),
      'public' => true,
      'show_ui' => true,
      'show_in_menu' => true,
      'menu_position' => 20,
      'menu_icon' => 'dashicons-images-alt',
      'show_in_nav_menus' => true,
      'publicly_queryable' => true,
      'exclude_from_search' => false,
      'has_archive' => true,
      'query_var' => true,
      'can_export' => true,
      'rewrite' => true,
      'capability_type' => 'post'
      );
      register_post_type( 'carousel-image', $args );
      } 

  function jd_bs_carousel($atts) {
     // Set Shortcode Attributes
     extract(shortcode_atts(array(
        'posts' => -1,
     ), $atts));

     // Start the Return String
     $return_string = '<div id="jd_bs_carousel" class="carousel slide carousel-fade"  data-ride="carousel">

   <div class="carousel-inner" >';

     // starting a new variable for indicators!
             $indicators = '<!-- Indicators -->
          <ol class="carousel-indicators" >';

  // The query
             $the_query = new WP_Query(array(
             'post_type' => 'carousel-image',
              'posts_per_page' => $posts,
              ));
              $i = 0;

             // The loop
             while ( $the_query->have_posts() ) :
                $the_query->the_post();
                  if ( $i == 0 ) {
                $return_string .= '<div class="item active">'.get_the_post_thumbnail($the_query->post->ID,'jd_bs_carousel_image').'<div class="carousel-caption">
              <h1>'.get_the_title().'</h1>
              <p>'.get_the_excerpt().'</p>
             </div>
             </div><!-- item active -->';

                                // The first indicator!!
             $indicators .= '<li data-target="#jd_bs_carousel" data-slide-to="0" class="active"></li>';
                }
                 else {
                  $return_string .= '<div class="item">'.get_the_post_thumbnail($the_query->post->ID,'jd_bs_carousel_image').'<div class="carousel-caption">
              <h1>'.get_the_title().'</h1>
              <p>'.get_the_excerpt().'</p>
             </div>
             </div><!-- item -->';
                 // Continue the indicator var
             $indicators .= '<li data-target="#jd_bs_carousel" data-slide-to="'.$i.'"></li>';
                               }

             $i++;
             endwhile;
             wp_reset_postdata();

                             // Finishing up the indicators var and add it to $return_string
             $indicators .= '</ol>';

             $return_string .= $indicators;

             // Finish the Return String and Clean Up
     $return_string .= '</div>

       <!-- Controls -->
    <a class="left carousel-control" href="#jd_bs_carousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#jd_bs_carousel" role="button" data-slide="next">

      <span class="sr-only">Next</span>
    </a>
  </div>';

     return $return_string;
  }

  add_shortcode('carousel', 'jd_bs_carousel');
