Gold borders around champs we earned a chest on in Champ Select?

I think it would make it a lot easier if we can see in champ select who we have the gold borders on and who we don't so that we can see who we should play if playing with the intent of earning a chest. I know alternatively we can keep a text document and keep track of all of the champs we already got chests on, but I think this would be a decent quality of life update.
