Need page break after last page

I am printing a purchase order which has the total line and the buyer signature at the bottom of the last page.

The user wants to be able to print additional information which could be a large number of lines.

I want to put this information after the signature line.

The print of the signature line is doing the    <?start@last-page-first:body?><?end body?>

It always wants to be on the last page no matter what I do.

Is there a way to get the signature line on the last page of the PO and allow this additional info to print after it?
