Please support mstest for MSBuild runner

I see that to run mstest as part of a build configuration, I have to select the vs2008 build runner.  I have a customized build and want/need to select MSBuild as my runner.

Can you please add support for mstest runs as part of the MSBuild runner?  (I could -- and do -- have a target in my MSBuild project that executes tests, but I want Team City to process and report the results.  I'm guessing that doesn't happen with the MSBuild runner).
