In order to manage appointment volumes, I'd like the option to add a buffer time to each appointment (ex. appointments are 45 minutes + a 15 minute buffer at the end, so 1 hour is allotted and I always have time between calls to file notes etc.) as well as limit the number of appointments per day so that even though I may have 7 time slots listed, once 4 appointments have been booked that day is no longer bookable.
