How to synchronize further CONTACTS to Z10 via BDS
 

We are planning to migrate from BES- to BDS-Infrastructure (using Lotus Domino 8.5.3). BDS works and now we are testing to synchronize PIM-Data.

But how to synchronize further contacts to the blackberry 10 devices?
Currently there is no way to configure this like in BES 5. (n)

This is very frustrating and I hope for help.
