Ad type based on role?

Is there a way to configure Classified Listing so that users with a ‘buyer’ role can only post buyer type ads and users with a ‘seller’ role can only post seller type ads?

I want to make it so Buyers can create their ‘Looking For’ ads only if they have the buyer role and sellers can post their ‘Selling’ ads if they have the seller role.

I do not want to limit by categories as both the sellers and buyers will be using them.
