Marketpress product post type

I am keen to use your marketpress plugin as i have been using your appointments+ plugin for some time now but need to setup gift vouchers for my appointments. I do however have Woocommerce installed which is currently using the post type 'product'. Is there any way to change the marketpress post type to something other than 'product' so this doesn't conflict with Woocommerce?

I cannot migrate Woocommerce to marketpress as the setup is very delicate.
