Signers Signature Position

To position an actual signature or initials block at the bottom of the last page, you'd simply have to know how many pages there are in the document and assign a signature to the bottom of the last page using X/Y coordinates. Beyond that, there is the ability to make the document simply a consent form, which would allow you to "accept" it, at the bottom of the ceremony window, but not apply an actual signature block to the document.
