Hosting meetings at the same time for other people - HELP!

Since I cannot schedule RC meetings on behalf of others for meetings independent of each other, but at the same time, if I reassign the HOST (sounds like it can only be done AFTER mtg starts), does the meeting then "move" from me to the new HOST I assign? Or, does this still mean I cannot schedule more than 1 meeting for anyone at the same time? I support 7 people who host meetings at the same time. HELP please!!!!!
