Zimbra OS 5 RC2

I am playing with shared contacts, email, calendars etc. Some of the things I want to do is to copy an email from my inbox to a shared mail area so other users can view this mail. I don't want to actually share my inbox. I can't do this as I only seem to have the option of moving. That means I can't retain the original email in it's original location. Likewise with appointments, playing with Zimbra desktop I wanted to copy some shared appointments so I could look at these when out on the road but I am only able set either the shared calendar or my own calendar when I really would need both. At the moment it is only an issue with shared folders but I can't help thinking the lack of copying ability will limit some usage.
