Deploying Test Complete Automated Tests

I have a similar issue just now. I have the full TestComplete (TC) IDE on my dev machine. We have integrated Test Execute (TE) into our build process which uses Team City. The TE instance exists on a networked VM. I have a global variable in my project setting which I use to switch between local and network mode, but I'm not able to set this via the command line. I can't use a stored global variable that is machine dependant as it also pulls down my TC script code from an online version control repository. So the project is always over-written before it is run. At the moment, we are relying on me remembering to set the gloabl variable before I push the project into the repository. I'd prefer if Team City was able to alter this variable at execution point. I suspect we'll need to look into running it via COM to get this though? Any further suggestions?
