Supporter Feature Request:: Disable "X" months

Feature Suggestion:

Currently you must select 1, 3, and 12 month price point options for subscriptions. I'd request each option have a default value of say "Off", which if set, would stop the option from appearing to the end-users.

We've got this hacked for our own use right now, but would be nice if it were in the official release so we're not having to edit on updates.
