Hi @HappyDragon,
Unfortunately not — but this would take Square to a whole new level for us too.
We just manually do this in store for regular customers.
One thing we've learned the hard way though (if you were doing this manually too), is if you change any services (ie names / times / prices etc), it doesn't apply to anyone who has existing bookings of that service (including recurring appointments). So good to keep that in mind (we just had a price increase, so had to go through and update our regular appointments to the latest service).
