We would like to eliminate the possibility of a user booking an appointment last minute and instead require that if the appointment was not made by 11:59PM the previous day, the appointment slots for the following day be unavailable. For example, a customer who wants to make an appointment for Wednesday 10/27 would only be able to do so until Tuesday 10/26 at 11:59PM and not earlier on that same day (e.g. 9AM 10/27 for an 11AM virtual appointment). Is this possible?
