Issue in displaying signature at the bottom of the rtf template.

Hi Friends,

I am facing issue in showing signature at the bottom of the rtf template.

The requirement is as below:

We are displaying SR and activities in the report. We can have more than one activity for one SR. Its a customer facing document, so we need the signature of customer at the end of the document. The issue is as we can hav 'n' number of lines in Activities we can not predict the the end of the page. we need to display the signature at the bottom of the last page.Currently it is getting disply at the end of the activity as shown in the attachment, which can be in middle of the page.
