I've had a question posed to me that I cannot seem to figure out, and didn't find anything in the forums or bugzilla...

Some users are used to (on our previous groupwise system) CC'ing managers on an group appointment - in that way, signifying that the manager's presence is not required, but in this way notifies them of some of their managed-staff are involved in this meeting.

So in Zimbra, how do you CC an appointment, or somehow distinquish between someone whose presence is required, and those whose presence is optional/informational? Is there a way, or is this an RFE that I didn't find (yet)?

thanks
