My client just added another service where she needs 20 minute appointments. Until now I have set the time to 15 minutes since all her other appointments fit the 15 min (except the 8 hour block which I also can't find a fix for). When I set the additional time base to 10 minutes I loose the ability to have 15 minute appointments. If I set it to 15 then I can't do the new 20 minute option. Please help!
