how to do upsells with CoursePro

Hi,

CoursePro is great! Best plugin in your portfolio!

I would like to be able to upsell courses, e.g. if client buys Course A, the thank you page upsells Course B and C (perhaps with a discount coupon to encourage instant action).

I know this is not built into CoursePro but perhaps there is a work around... As the makers of this great plugin, what do you imagine is the best way to handle upsells using Course Pro?

Thanks!

David
