Turn off "stop executable" dialog in xcode when running app?

The "stop executable" dialog that comes up every time I h开发者_JS百科ave an app already running in xcode and rebuild and run is really annoying me. Is it possible to turn this off and auto-stop any running apps?

Thanks

EDIT: They've added an option in Xcode 4! Awesome!

Looks like there is no way

You can hit shift-cmd-enter to kill a running app, that's the "speedup" I use. Don't know if it's faster than hitting enter when that dialog pops up though.
