Having an end date for a pass or edit meeting date#1757

It would be very helpful to have start and end dates for scheduled group passes, especially for groups that run throughout different times of the year.

A calendar-style option to edit or delete a group pass for just one specific week—without having to delete the entire series would improve flexibility and usability.

Summary of suggestions:

1. Add start and end dates for group passes.
2. Allow individual weeks (dates/times) to be edited or deleted without removing the entire group pass, similar to a calendar view.
