Appointments - Option to keep it appointment in list when capacity reached
I have set up one time events for instructional classes we offer. Each class has a capacity of approximately 12 people. When the capacity is reached, the event/appointment disappears from the list since in theory a person is unable to book that appointment/event. Is there any option to keep the event in the list, but just gray out the action button? I want students to know that there was a class offered on that date but that it is full. I would like to instruct people to contact us to be placed on a waiting list but they can't do that if they don't know there was a class that day.
