Locking Info to bottom of last page

 I have created a BI Publisher template and want to display some text at the bottom of the last page of a multi-document multi-page output. I created a 'signature' template with-in the template and put it after the <?end section?>. 

<?end section?><?call: signature?><?end for-each?>

This puts it on the last page but immediately after the existing information. 
I want it anchored to the bottom of the last page not appended to the last information. 
I tried doing this with the Footer but I just want this on the last page.

Any help is appreciated.
