Launch Composite Project from testrunner.bat using custom settings.xml

I am trying to figure out if there is a way for me to launch my composite project from testrunner.bat and tell it to use a settings.xml file that is in a custom location, not the one located in the composite projects root level directory.  Is this possible?

I can call it just fine using the command below and using the settings.xml in the project directory.

cmd.exe /C testrunner.bat -s"%soapUITestSuite%" -c"%soapUITestCase%" -t"%soapUIPropDir%\test-settings.xml" -E"Default environment" %soapUIProject%

But I can't figure out if its possible to tell it to use a settings.xml located somewhere else.

Thanks
