Synchronizing shared calendars / contacts


at the moment, on an ActiveSync account synchronized via z-push, only the personal calendars / contacts are sent and synchronized.
Is there any possibility in the protocol to support also server shared calendars coming from another account?
For now, the only way is to create another account on the device with the credentials of the shared account, and this is not always a good choice, also because the sharing user may wish to share only certain resources.

I read somewhere that this is not considered in the AS protocol, so it’s not possible as a standard.
Is it true?
Any trick already implemented to support this?
