Problem:
I want to add a group of users to a meeting as invitees. But it is complicated to add a them one by one. So I add a project as attendee. But it is only displayed as one attendee, the project members are not displayed. The Project-members then get only a notification that the event is created but not that they are invited. also if they open the event there is no Accept or Decline Button as there is one if they are invited per person.
Possible Solution:
Display Project Members as well as the Project. Notify the users that they are invited.
eg: with some sort of nested List:
