store categories in url

What I meant to ask is, since it is possible to do this shortcode [wpsl template=”default” category=”fast-food,italian”] or this shortcode [wpsl template=”default” category_type=”checkboxes” category_selection=”bmw,mercedes,porche”]

is it possible to have multiple category names on the url like this:
http://yourdomain.com/your-store-locator-page/?wpsl_cat_name=bmw,mercedes,porche
