I am configuring a Build Project that attaches to multiple VCS roots. My first step is a Powershell script. In the Build Step configuration, I am asked for the working directory for the script. Is there a way to tell it which VCS root to use? I can give it a relative path for the working directory if I can tell it which VCS root to use. This is very straightforward with one VCS root, since there's no doubt about which root to use.
