Affiliate Restrictions??

Hello!

I really want to use the WCFM Affiliate plugin instead of purchasing another one, but I don’t see a way to limit an affiliate to a specific vendor and/or product? I want vendors to be able to recruit affiliates to sell ONLY their products on the site without worrying that the affiliate will sell other vendors’ products, or for vendors that don’t want an affiliate to not have an affiliate promoting their products.

Is there a way to do that? Or some code I can add to get this done?

Thanks!
