We need an auto Time Block at beginning of appt for NUMBING for certain services provided (filler, microneedling, etc.)

Currently what is offered for time blocking with each appt is: Processing Time (a block of time at the END of the service when a client is busy, but the staff can attend other clients.), Finishing Time (a block of time at the END of a service and any processing or transition time when both the client and the staff are busy.), and Transition Time (a block of time AFTER the service is performed during which the staff member is unavailable. Use this for cleanup, buffer, documentation time, break time, etc.)........ there is not block of time at the BEGINNING of a service to allow the provider to see other clients & to allow for double booking in this time frame while the patient could potentially be numbing for 30 minutes.
