Hide specific level & allowsignup using a direct link.

Pro Sites – Is there a way to Have a “Level” be invisible (with the box not checked) and still have someone be able to access it to join via that subscription? via some kind of link?

Also, is it possible to have one version of the “upgrade” page that has the coupon code and one that does not? or are we int he same boat?

I suggested we could possibly hide 1 of the levels with CSS, but the sign up using link to that level is the biggest issue. Not sure how difficult this would be to achieve.
