I agree with this but also adding a time limit/expiration for the rolled-over credits (i.e. only valid for 1 month after the rollover) so people can't bank obscene amounts of credits. It would be great to have this expiration date controllable by the admin in the Settings section. (Or turn it off there if you don't want to set one.)

This would be a game changer for my studio

I agree! Please add this feature :)

Agree! Would like this feature too

And the option for the same for punch passes.

That would be helpful!
