ListingPro & Exclusive listing

Anybody know how to do the Exclusive Listing option on ListingPro?

I have tested adding and approving a test Cafe and made it an exclusive listing. Went back in and was able to add another Cafe in exclusive listing even after the first one was approved. Should there be a cross-check somewhere to dis-allow this from happening?

If a customer pays for an exclusive listing in his category, the category should then be locked out, especially if it’s in the same city…or am I missing something?
