Anonymous Blocks Edit

How can I convert anonymous blocks to regular blocks?  In AutoCAD this method works http://www.draftsperson.net/index.php?title=Anonymous_Blocks_in_AutoCAD, however it doesn't work in DraftSight.  I have an issue with the generated BOM does not meet our company's standards so I have to add a manufacturer column and I rather edit the generated BOM rather than start over from scratch.
