CoursePress Pro course bundle request

I have searched the forums, and asked in Live Support, but have not found a way to do this, so I think it needs to be a feature request.

I would like, and I immagine many others would too considering the nature of online training, to bundle courses together in a single product, but still be separate courses.

My current workaround is a bit ugly, but will work, and that is to setup a membership system in which I sell memberships, then each bundle will be associated with a different membership.

Any better suggestions are more than welcome!
