Roster order?

Hi Guys

We have OpenFire tied into our A/D.  When ever we add a new group or make a change, the order of Roster changes. So if I added a new group for "Sales" for example, this might end up at the top of the list.

Is there anyway of specifying the default order of the Roster? I need to keep it as

Directors

Sales

Customer Service

IT

etc

I know people can drag-n-drop the order in the client (Pidgin), but I need to automate this.

Thanks
