Watch out, though.
It does not save any days or times you may have blocked off for vacation or holidays. You have to reenter them after updating the schedule.
This fouled us up the first time we did it.
I've redone my schedule a few times. It has started to duplicate every hour of the day and duplicate lunch breaks and so on. Is there a way to completely reset the schedule system, but not lose patient appointments?
Both are true and possible.
If you already have appointments when the new schedule is made, it will keep appointment that are out of range for the new one (if you had a 6PM appointment and now it is set to 5PM on that day.)
Break times and blocked times are NOT, to the best of my knowledge, kept when the schedule is reworked.
