TOPIC: Link to include location and category

Hello,

I'm trying to create links to associate with locations and categories.

I have several locations, and several categories.

I want to have the possibility to link to a listing of events, manually, that shows the stated categorie(s) at the stated location.

When I switch SEF and Rewrite urls to off, I get this url when I browse to location:
index.php?option=com_dtregister&view=event&layout=locationlist&controller=event&location=2&Itemid=528

Can I add something in there to make it show only from a certain category?
