Allow students to book multiple classes all at once, for different dates and times.
With group class scheduling here's the scenario: In person group class meets Tue/Thu from 5:45-6:30pm most every week. When students sign up for that class, they are automatically enrolled in all available sessions.
Then, I'd like to be able to track attendance for all enrolled students each class period (similar to what's available for appointments) - if they don't show up, or if they let us know ahead of time that they wouldn't be able to make it a particular day, or if they attended.
