When creating a repeating or standing appointment, it would be extremely helpful if the system displayed a preview list of all the upcoming dates that will be scheduled.

I’ve used another scheduling software that included this feature, and it made a big difference in preventing conflicts. Being able to see all future appointment dates in advance allows you to immediately spot if any fall on holidays or planned vacations. You could then easily adjust the frequency, modify a single appointment, or set an earlier end date before finalizing — instead of having to go back later and make multiple edits.
