Visual Studio solution with multiple ASP.NET web applications

I've got a Visual Studio 2010 solution that has multiple web applications in it. I've set one as the startup project but when I debug Visual Studio is starting up a de开发者_StackOverflowvelopment server for each web application in my solution. Is there anyway I can have Visual Studio only start up the development server for just the default startup project?

At the website (or project) level, set "Always Start when Debugging" = false (the default, as shown in my screenshot, is true.)
