Thread: Permalink structure

Permalink structure

I am building a local directory and hoping to expand it to other cities at later stage.

I currently have the permalink structure as such: www.sitename.com/%category%/%postname%/

But the problem is that the above structure works with the posts only.
When I am adding a listing I receive the following structure: www.sitename/listings/listingname/

I want to have a permalink structure as such: http://www.sitename.com/cityname/cat...me/listingname
I really appreciate your help!

thanks!
