...those recurring appts change automatically as well to that timing.

I have clients that book a year out and have recurring appts, say every 6 weeks. If I see that their appt should be 45 minutes long instead of 30, when I change that next appt, the recurring appts also change. I have had to go through manually and change all 45 minute color processes to 30 (they normally are 30) and some people that take longer in cutting or color individually. It has taken me about 3 hours just to change from today 9/12 to the end of the year in December. Whew!
