Courspress Pro - change link on marketpress cart 'Continue Shopping' button.

I am using Coursepress Pro and the included Marketpress to sell online courses.
As I am building my own templates (to get a better design to match my theme), I noticed once I add a product to the cart and hit the 'Continue Shopping' button, I get sent to the Marketpress store product listing.

I don't use this, and don't want to use it. I want to use my own page for the listing of courses.

Any thoughts on how I can change the continue shopping button link from /store/products to /courses ?

I would prefer this wasn't changed in the plug-in core so I can continue to update the plugin in the future.
