Champ Select Reporting

I am just wondering if there is a way to report people for what they say/do in champ select, or if it is only possible after game. I just had a champ select where a player called me an n'er roughly 15 times in champ select because I would not dodge for his friend. Why are we not able to report stuff like this?

PS: Just because my name is douchecanoe does not mean i am one ;)
