This is a great feature request, and already has some traction in terms of votes.

We're monitoring it, but also this is the type of feature that seems simple on the surface but once you peel back the curtain it gets complex quickly based on the face that "is this form recurring" is a complicated question: forms can have recurring options for just one level, or for all levels, or they can be donor's choice recurring which would then toggle on and off the recurring status on the fly.

It's not impossible to accommodate this feature request, but it's certainly complicated.
