Setting license level permanently for a user in Terminal Services environment

Hi

Using ArcDesktop 10.1 on Terminal Services, I'm trying to find a way for setting the desired license level once, affecting only my session.

I'm aware of the Environment Variable workaround, but it would only work for Context scope (meaning I have to launch the document / application in the same scope), or as a permanent System Environment Variable.
Adding it to the User Environment Variable won't affect the license level.

Any help will be appreciated!
