MarketPress sell custom post types?

Is MarketPress multisite configurable to sell custom post types?

For example say we need to setup a marketplace of stores selling photo id cards, where a visitor goes to a store of their choice, enters some information in a form and is then after checkout is presented with a custom view (post type) displaying a template that reformats and styles some of the information they submitted?

If this is possible, is there a way that the custom form fields can also be displayed on the sold items list within each store?
