PasteBox XT is a free XTension courtesy of Markzware which has been developed per a user's request for an XTension that allows pasting of a cut or copied box to its original page position.
Using the "drag tool", select a box on the page, then select "Cut" or "Copy" from the Edit menu in the usual manner. Then when you type command-shift-v a duplicate of the original box will be created on the current page at its original position.
