How can I determinate the document last page in a .rtf template with BIP Microsoft Word?

Product: BI Publisher With OAS

Version: OAS 7.0

Hi, I am trying to create a .rtf template with BI Publisher in Micorsoft Word. As a way of testing, I want to write a word in the document footer and reference it in all pages except the last one. In the last page I want to write another word. I wish to know if it exists any BIP sentence representing the document last page or maybe any condition for doing it with a conditional. I used this sentence but it throws me an error by generating the report.

<?start@last-page:body?><?end body?>
