"Unauthorized" PO RePrint

Hi All,

Can a PO be re-printed with the Authorized signature? 

One of our PO end-user sets up POs in advance.  Well before sending them out to the Vendor.  In some cases, the PO needs to be changed...ex. new price information.  They don't want to do a "Change Order" to get authorized signature to print.  Reason is that the PO was never initially sent to the Vendor and they don't want the "Change Order" to appear on the PO the first time the vendor receives it. 

Is there a way to get the authorization signature to be printed when clicking on the hyper-link "View Printable Version".  Currently it prints this way with "Unauthorized".
