Is there any easy—or even merely "usable"—way to set up a recurring event with a rotating guest list? IE, I have a meeting event which reoccurs every day. I'm in it every day. Three other people rotate through it weekly: i.e. Dave is in it every day this week, Jane is in it every day next week, Sue the week after, then it's Dave again. And then the rest of my entire department rotate through it daily (25 people, a new one each day, and then we loop around to the first one on day 26). Is there any way at all to automate this (or even just part of this) or do I need to edit the guest list for each instance of the event manually?
