Let the reservationist control when an email alert is sent to a therapist stating that they have just been booked to provide a service. This will allow reservationists time to move appointments around on the schedule and perform other adjustments before alerting the therapist regarding final arrangements.
Currently, booking alerts are uncontrollable and precipitous. Therapists often receive booking alerts before the reservation has been finalized, so if the expected appointment does not show up on their schedule after all, or in the way the alert told them it would, therapists become confused.
