Can the report template for the RQM PDF reports be replaced?

In RQM, Test Plans and Test Cases (among other things) allow you to export the data in PDF format using a button near the top of the screen.  My customers like this report, but need to add things to the Master page of the report Template before it can be presented to their customer. Where are the templates for these reports located and (more importantly) can they be replaced?

We've successfully done this with reports on the RQM Shared Reports page.  We located the JAR file that contains the templates, modified the template and replaced it on the Report Resource page.

Thanks in advance.
