Is it possible to add additional fields to sync with the contacts on the phones?

We have some users who use the "notes" fields in contacts which gives them a bit of information on the contact. This syncs fine on a BlackBerry using BB server, but we had to edit the field.

On the DS server it doesn't sync over and I was wondering if there was a way to make it do so. I am going to poke around the server and see if I can figure something out, but thought I would ask to see if anyone else knew.
