Upsell Bundles

While I see a course can be turned into an upsell, I'd love to be able to assign a bundle as a sign-up. I price my courses so that it makes MUCH more sense to buy them in a bundle. So, I'd love to have some way to have a student log in and see their one course with an option to buy a bundle. Right now, I make a lesson in the course that pitches them the bundle. I loved it when I logged in and saw a course I didn't order (and available for sale) I was like "Cool," but you can't do that for a bundle.
