Changing a meeting host

I am trying to figure out how to work in Zoom scheduler/meetings.  My firm has several types of meetings and a few different people who rotate taking meetings based on knowledge and capacity and we are trying to come up with the best way of handling that without the need for an ungodly number of booking pages.  

I tried setting up a booking page for one meeting type as an "any host available," but it defaults to only one of the group of hosts no matter how many meetings I schedule.  Fine, but when I edit the meeting to make someone else the host, it doesn't remove the meeting from the original host's calendar, notify the client, or notify the new host.  Is there a way around that?

The booking pages are also allowing for overlap between scheduled meeting types.  While testing this I was able to book more than one meeting at the same time for the same host.  How do we ensure that doesn't happen?

Thanks!
