Catalook subcategories

Hello,

I have issues making catalook urls nice. What I have is main categories, and subcategories. I've managed to achieve something like this:

http://www.domain.com/pro...tegory2ID/42/Level/2

My problem is this part: /List/1/Category2ID/42/Level/2

I need this URL to look like this:

http://www.domain.com/pro...name/subcategoryname

Can this be done? Any help would be much appreciated. Note that these are NOT Advanced categories, these are standard categories with subcategories.
