[Plugin: WP e-commerce] Want category query to make specifically-styled subcats

I’m using the category_query process to list my site’s product categories on the home page within some styled boxes I have set up. I’d like to bring in the subcategories as well under each parent category and I can, except the query gives all the subcategories the same styling as the parents and that’s not what want – I want to be able to implement separate styling for the subcats.

Here’s the code I’m using:

<ul>
   <?php wpsc_start_category_query($category_settings); ?><?php wpsc_start_category_query(array('category_group'=>  get_option('wpsc_default_category'), 'show_thumbnails'=> 1)); ?>
	<li class='latest_product'>
	    <a href="<?php wpsc_print_category_url();?>" title='<?php wpsc_print_category_name();?>'>
	      <?php wpsc_print_category_image(145, 105); ?></a>
		   <div class="product_info">
		      <a href="<?php wpsc_print_category_url();?>"><?php wpsc_print_category_name();?></a>
		       <?php wpsc_print_subcategory("<ul>", "</ul>"); ?>
		  </div>
  </li>
	<?php wpsc_end_category_query(); ?>
</ul>

A quick illustration of the output I want would be this:

<"latest_product" li>
      <parent category group thumbnail>
            <"product_info" div>
                 <parent category name with link>
                      <ul, perhaps with a class name so I can style it>
                           <li>any subcategories for this category</li>
                            <li>any more subcategories for this category</li>
                       </ul>
              </end "product_info div>
 </end "latest_product" li>

Anyone know how I can do this?
