Add multi-day class functionality & reminders

I have classes that have multiple sessions (i.e. the same group meets 1x a week for 3 weeks on 3 specific dates/times). I’d like to be able to have auto reminders sent to them a day before each session.

I’d also love to be able to disable the date/time selector for these classes since they are set dates & times rather than appointments at variable dates/times.
