Marketpress template files

I am creating a site using a mix of marketpress and appointments+ and the problem is that it seems that marketpress doesn't come with any custom template files for products, because my first appointment product is using a regular post template.

If I want to use appointments + and also offer other kinds of products, they will share the template and will be good enough for one, weird for the other one.

I mean you know that the way appointments+ works is not with a regular add to cart button and that's why the integration with marketpress was a solution when looking for more than "book a single appointment"

I guess I could have a template per product category? What about guidance about making a template for marketpress that will make the appointment as product work?

It'd be good if marketpress came with some basic template files.
