Marketpress Plugin and SEO

Hey There, I am using the marketpress plugin for a client's site. It's setup for a referring link (like affiliate) that directs the visitor to another site where they can actually make the purchase, so only presentation and general tabs are showing.

I am also using Genesis framework which has SEO for pages and posts. I like being able to add the products with marketpress, but can't see where I can add product specific title, description, and keyword. Am I missing it somewhere?
