How to add Document History to signed docs

For executed contracts, I need to include the Document History validating the electronic signature.  I have a Business account and have selected the "Attached Audit Report to Completed Documents" button in the Global Settings tab.  The Document History is now sent as a separate .pdf file with the signed document.  To properly identify the signed document, I need the Document History to be included as the last page(s) of the .pdf file containing the signed document.  Can this be accomplished?
