Ok, I have now read a lot and also studied the Git Extensions manual for some time. I have tried basically all available combinations like [Central_Repo]source
or $(CENTRAL_REPO)source
. It seems like there is no way to use a windows global variable or any other variable to state the URL of a Repository.
In case anyone got a different answer later on, I am happy to hear it!
