Category links

We are using categories to group places by US counties, since GD doesn’t have a way to set up counties in the location hierarchy.

GD allows us to add country > region (us state) > city, but not country > state > county > city. To get around that limitation, we are using categories for counties which in this site are wine regions in California.

Using categories in this way is resulting in some weird linking in the details page. For instance, if you go to this detail page:
http://www.winetasting.com/winery/california/woodside/chaine-dor-vineyards/
you’ll see that the winery is added to category South Bay Wineries. When you click on that link in the sidebar under “wine regions” you are taken to a page that filters by city and category: http://www.winetasting.com/winery/california/woodside/bay-area-urban-wineries/south-bay-wineries/

Is it possible to change the behavior of the category link so that instead of linking to the existing hierarchy that includes the city, the link instead goes to the category main page such as: http://www.winetasting.com/winery/california/south-bay-wineries/

We think that the existing link wont make sense to users who are expecting to link to the category and not the city within the category.
