Exclude certain groups from reminder notifications

First off, thank you so much for the reminder feature! It's helped my team stay on track when life gets busy.

Problem:
We do not require certain roles to attend our midweek rehearsal. With reminders turned on for rehearsals, every scheduled person gets the notification.

Request:
Add group selection to the reminders.

Example:
Rehearsal reminds the Music Team and Tech Team an hour prior to the rehearsal event
Service reminds all scheduled people in all groups one day prior to the service event
