Hey @fredericksia1991 !
It’s the Full Calendar Scheduler Suite
If you’re interested, I can set you up on a trial so you can try it before you buy it! A couple weeks should be plenty of time AND I offer support setting up as I don’t have all the docs for the Timeslot generator. But I am very available and it’s actually fairly simple to use!
I’d wait to use it until my next update goes through. I’m waiting for almost 2 weeks now. The update introduces some breaking changes and correlates with the documentation. Either way, I’ll provide support throughout!
