Is there a way, using Windows GPO, to set up a list of "default" mapped drives that can be applied to a group of users?

I runs small network and would like to make sure that certain groups of users (like Sales or Support) have the same network shares mapped to the same drive letters irrespective of which PC they log onto.

This would make the setup of new users easier and allow the centralised administration of the network locations shared.

Any links to examples and/or step-by-step guides would be greatly appreciated.
