Tagging the best games

I would like a method of tagging great games I play.

You have those fantastic games you wish you could keep forever for certain plays, like team fights, or laning phases. Support is autofilled more often then anything, its rare that you can carry a game as ADC without a great support! I just had a fantastic Blitzcrank, he was autofilled support. He, and he alone, let me carry that game! I know riot is doing updates to the honor system, but this could be an extra bump for the best of the autofilled players, reward them more for doing well when autofilled! (extra IP for winning autofilled games is a good idea) instead of saying "we have to take our turns filling". This is a horrible business method!! Riot please, that's a horse shit reason of processing. Don't punish them reward them!
