Show if there is a waitlist on the Expanded Scheduler

I love that you added the FULL icon to the events calendar and the expanded scheduler on the admin side.  It would be so very helpful to have a waitlist icon also visible as soon as someone is added to the waitlist. Currently, we manually add a display message as a heads up that there is someone on the waiting list. Otherwise, staff is not aware that there is a waitlist from the expanded scheduler.
