Add 2 o more instance of "Portal" into app

Hello, I would like to point the portal wordpress link into the app to a specific category.

To do so, I’ve modified this line:

function ttwp_blogs()
{
    global $wp_query, $post, $wpdb, $tt_timestamp_filter;

    $args = array(
        'offset'                => isset($_GET['page']) ? ($_GET['page'] - 1) * (isset($_GET['perpage']) ? $_GET['perpage'] : 20) : 0,
        'posts_per_page'        => isset($_GET['perpage']) ? $_GET['perpage'] : 20,
        'cat'                   => isset($_GET['category']) ? $_GET['category'] : '',
        'ignore_sticky_posts'   => true,
    );

'cat' => isset($_GET['category']) ? $_GET['category'] : 'ID OF THE CATEGORY',

Now, I would like to another instance of “portal” ( create another link into app ) to point to another specific category.

Is it possibile to do it? Could you help me to do it? I’ve not the skills to do it.

Thank you in advance
