Can I start 2 out of 3 mock services in one project using MockServiceRunner.bat?

I have a project containing 3 mock services, but I only want to start 2 of them using the MockServiceRunner.bat file.

I can start one (using -m switch) and all of them (just supplying the project xml file path to the bat) but I can't work out how to start 2 of the 3, or if this is even possible.

Thanks
