We don't have A/B schedules yet, but we’re working on them this summer! We definitely understand how important they are!
That being said, we have a ton of teachers who work around this now. They simply turn all their classes "on" in the setup screen and then on Monday, go through and quickly turn any classes "off" that they don't teach. We realize it isn't ideal, but it usually takes teachers less than 2 min a week.
