[I've added it here](https://github.com/guardian/frontend/commit/8d7e0d7e4f5a3ce5ee78839fb5ab414052cfcdf2).

With your snippet there was a little bit of syntactical compilation ballsness that I didn't understand enough, so I did it the way I know. Seems to do what we were expecting from yours.

I have to merge this morning though - so we can catch up and refactor if need be, but the result is what we want and works for all competitions now.
