Add-on inventory and deletion after use

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

Total Available is overall add-on inventory, not a one-per-registration cap. An inventory of one leaves only one unit for all registrations. Ordinary deletion is blocked when completed registrations use the add-on. The add-on editor has no Hide control; manage further availability with supported quantity/restriction settings as appropriate, or have support review the existing purchase/history before removal. Adding a replacement registration question does not remove an already purchased add-on.
