Visual Studio: Set default project on project or solution settings

У меня есть решение Visual Studio 2010 с несколькими проектами. One of the projects is set as the default project, but I want to change that by default.

I know that I can right click the project I want to be the startup project and select "Set as StartUp project", but this setting will be stored in the user's files (.slo and .user files).

As a company policy, we don't check these files in the source control system, therefore when another user opens the solution it will have a different project as the startup object.

Is there another way to set these values? Something like a setting on the .sln or .proj files?

Thanks
