At current the waitlist is a post it like system that is great for allowing our clients to put potential appts onto the schedule, but once something is deleted or scheduled there isn't a way to determine what used to be there in the event there is a mistake or any follow-up needs to be done. I am envisioning on the History tab on a client that it shows Waitlisted appt for the appts that are waitlisted but not scheduled and also a cancelled appt for any waitlisted slot being canceled or deleted.
