I'm not exactly sure what I'm going to do with this, as I don't know what is available to me. Plus, I would need to automate this process in some way and that would take some time (I can't do this manually, as I have already two dozen messages just like yours just from last evening). For now, my suggestion would be to just include VoiceAttack in your Steam library, as they will be the same app with very slight differences.
Hope that helps!
