Restart Ranked Series?

Unless there's a way to do this that I don't know about-- I think it would be good for some people to restart or even just end their ranked session.

And what I mean by restart is to erase all previous ranked history and begin the 10 ranked solo queue games all over to be placed again.

Seems my games have just been bloody awful lately and I think the option for a fresh start to attempt to do better would be nice.
