This isn't actually a good idea. You don't want U turns at the end of dead end roads, generally.
I've seen, personally and in the forums, instances where routing will think going down a dead-end and turning around at the end is better than finding some other legal route.
If you're going the wrong way down a dead-end, Waze will give you a route line and tell you to proceed to the highlighted route, basically.
