Deleting Duplicate Document Folders That Are Under A Single Parent

It would be nice to help clean up the trees that have multiple empty document folders that accidentally get created under a single parent item.  For example if 5 document folders accidentally get created under 1 Purchase or Rental PO, it would be helpful to be able to delete those empty folders.  I know you can move them around but it is still time consuming to open each one to ensure there isn't anything in them.
