Limit who to invite in the events

In some communities could be interesting to let specific users create events. For example, users with a particular role could be allowed to create events.

The problem is that those users could invite anybody. There is no way (as far as I know) to limit who they can invite.

They can invite users with any specific role and users that belong to any group, and they can even decide if they want to invite people that don't belong to the community.

I wanted to limit who they could invite, so the users with role X could create events, but there wasn't any way to invite users with a particular role or belonging to a specific group.

Imagine two parallel communities in the same Heartbeat: one for students and another for members that access the community using a different path than buying a course. I don't want them to participate in the same events.
