series meeting with two Event organizer, with the same rights

Customers have a standing meeting (meeting series) which should have two hosts, as it is a joint meeting of two teams with the same area of responsibility.
Normally it is fine, that there is only one host, but in certain situations it would be important to have a second host or a co-host:

• Planned absence of the host; e.g. vacation, training, …

• Unplanned absence of the host; e.g. sick leave, …

In this situation there should be a controlled conference moderation with the co-host having the necessary rights
