Request for match history always showing Grades on PVP games that aren't custom games.

For a points in a clan's system for accommodations, we need screenshots proving we have recieved a S+ and it doesn't always show up in matchmaking and if we close the end game screen it's lost forever. Would also be nice in opening full match history online to have older games show grades please.

Thanks for your time any future RIOT developers in patches for reading, that might make this happen 0:~)
