Adding a List of Members to a shared workspace
 

A question about workspaces.

For a document that is going to routed repeatedly, I would like to add a
list of members to a shared workspace, and then assign tasks to each
individual. A contact list exists in both Outlook, and the Sharepoint site
that is hosting my workspace. Is there any way to add lists of members to a
shared workspace without adding individual email addresses?

Thanks
