BlackPoint and Document Sets

I'm new to K2 BlackPoint and I'm designing a Document Management System.  Individual documents and Document Sets are going to be intermingled within multiple document libraries.  I have a requirement to move the documents and document sets to different libraries during the workflows.  I have been unable to find a way in K2 BlackPoint to move or copy a document set in SharePoint 2010.  Has anyone done this and could you point me in the right direction?  Thanks
