location of report template files

[aTestLinker]

Does anybody know where the template files (tpl) for reports are stored?
I'm trying to display report of all testplans associated with the given build using the report format of resultsAllBuilds. I got the correct results but for display purpose, i need to change "test plan" to "buildname" and "buildname" to "testplan". I'm assuming I need to change that in the template but I don't know where the template file is.

In the same place where all tpl are -> gui\templates.
