Classifieds Categories and WP Categories

Hi! I was wondering if you can integrate the WP categories with the categories that you can set up in the Classifieds plugin. I've already set up categories in WP so that they will show up in my sub-navigation bar on the home page. I would like for a user to be able to click on a category on the home page to see the classified ads for that category. If there isn't a way to integrate them, is it possible to display the Classifieds categories in a navigation menu on the home page?
