Advantage Using DS Premium verses Free when using an ePDM system

Were currently are in the process of switching our 3D CAD system to SolidWorks and are using the ePDM system.  The 3D side has been clearly explained but in the division that I currenly reside we only use 2D drafting and are looking at DraftSight.  I have been able to create blocks that link to the data cards in the ePDM.  This seems to work well, but what I'm having problems with is when I have multiple block attributes of the same name in different areas of the drawing.  I can not seem to link them all together.  Example is the Revision level that increments when we go through the approval process in ePDM.  It only updates in one loctaion on the drawing.  Would the Premium package do more for us software wise or is just the way it is?  What other advantages would the Premium offer us?
