We had an issue recently, when someone from our team accidently book an appointment at 1am, when it should be at 1pm. It would be great to have a feature that allows us to block any attempt to book appointments outside our working hours in our roster to prevent this. Since the booking was not visible in our calendar view, no cleaner was assigned and we had a no show, as both our team and clients though it was booked for 1pm on the day.
