Ability to Limit the Number of Membership Add-ons Available
We have a parking program with a limited amount of spots available each semester. Is there a way to apply a limit to how many memberships can be sold in a membership program per year? Or can we offer a parking validation as an "Add-on" but have a limited amount available? Currently we have set up Parking Validation as an inventory item that the seller must also select when selling a parking membership. This way we know how many are available, but there comes the problem of remembering to add the inventory item with the membership. Is there a better work around?
