Possible to add sub-category name next to the topic name in the 'Categories with Featured Topics' view?

Does anyone know if its possible to add, via CSS, the name of the Sub category to the topic list in the ‘Categories with Featured Topics’ view? I know ‘Categories with Latest Topics’ has the category already. But we group our discussions into types of discussions (Regional dining, home cooking, drinks, etc.), and they don’t really mingle together. So the ‘Categories with Latest Topics’ don’t work well for our forum since they list the topics by time, regardless of categories.

Thanks for any pointers!
