Multiple Calendars & Addressbooks?

Typical usage for our users -- for a given, single account -- is to define, use & sync multiple Calendars & Addressbooks.

We currently do this using CardDAV and CalDAV clients; easy to set up, works perfectly, but obviously not integrated into a push/ActiveSync solution.

IIUC -- and I may not -- ZxMobile does not support multiple instances of either Calendars or Addressbooks.

In forums, here, I've read comments that it's a 'limitation' of Android. Since we're _doing_ it successfully with Card-/Cal-DAV, I'm unclear as to what the actual limitation _is_.

So, step 1: Can you clarify if/when/how ZxMobile can be configured to support per-account multiple Calendars/Addressbooks?

Thanks.
