No ability to schedule backwards

In Updated Scheduling you can accidentally schedule/reschedule backwards. So if a patient called and rescheduled something from Dec 2022 you could accidentally schedule if for April 2022 if you aren't very careful. We are so busy and have so many calls coming that everything we do is asap and this has happened more times in our dept than we would ever like it to. This causes a problem because you think you are scheduling for now, but its last year or last week. EX: You give the patient an appt. for next Monday but its actually scheduled last Monday, so they show up today and you don't have any openings and they are not on the schedule. We should not be able to schedule backwards AT ALL but at the very least something should say "YOU ARE GOING BACKWARDS ARE YOU SURE YOU WANT TO" or something like that.
