SEO in Marketpress

I was wondering if SEO options would be supported in a future version of Marketpress. I am specifically looking for an input for the meta description so that one can control what is displayed in the SERPS for a given product instead of an excerpt of the product description.

I am using the Headway Theme which has a great SEO section for posts and pages, but that is not available on the Marketpress pages. Should I perhaps ask Headway to include their SEO on custom post types instead?

I have not tried the SEO plugin from WPMU Dev yet, and don't know it that might help with this.
