Fax appointments in updated scheduler

We currently have offices that want us to contact their patients to schedule and call them as well, with the staff we have that is not practical at all. In the end the offices end up calling us to ask when the patients are scheduled, which causes stop times as well. It would be nice and efficient if the ability to send the appointment via fax through the scheduling system were an option, that way the office would have the patients appt and would also be helpful for reschedules to alert the office.
