Hi All,
Each computer can have a different time slot size. But each schedule on the same computer will have the same size slot. There is currently no way to have different size time slots for schedules on the same computer. You can make different appointment times. They will fill the time slots as needed. For example if you have 15 min slots. It will take three 5 min appointments or one 15 min appointment before the slot is seen as overbooked.
