I have several mr configurations in different directories (this helps me to synchronize groups of repositories gradually). In man mr, it is stated

--config mrconfig
       Use the specified mrconfig file. The default is to use both ~/.mrconfig as well as look for a .mrconfig file in the
       current directory, or in one of its parent directories."

How can I skip checking all repositories in ~/.mrconfig if I explicitly ask to use another config? I managed to solve that with -n option, like

mr -c mrconfig -t -n 1 status

but -n 1 looks a bit redundant and wrong for such case (I know that I can skip the -t flag with .mrtrust).
