Yup! I do it all the time. In fact...
Go download https://bitbucket.org/privateteamogre/scriptextensions/downloads/OgreUtilities.tcx and follow the help instructions for installing a script extension. There's a method on that object (ogreUtils.getTCCommandLineParam) that examines the TC command line for any parameter of the format /<parametername>=<parametervalue>. Feel free to adapt and use it however, as a courtesy, please give credit as due.
Thanks Tristaanogre, I'll take a look at it. If we do end up using it, I'll be sure to put credit!
