The Google Analytics tracking snippet for subdomain tracking is slightly different than the default tracking snippet (it has one additional parameter).  I'm trying to update this in DNN, but after about an hour of Google searches and scouring the FTP server... I can't figure it out.  Granted I'm not a programmer, but this is a change that takes about 30 seconds on WordPress, Drupal, Magento, etc... so, I'm getting pretty frustrated.  Can anyone please help?

Thanks -
