Having more than 3 mastery 7s doesnt feel rewarding

I'm aware this is a pretty petty topic but at the same I'm sure there are others out there that can agree on this. I feel like there should be a way to show every single champ you get mastery. I understand there's an "in progress" category so when u hit mastery 7 on a champ they no longer show in it. There should be a "mastered" category so that way you can feel better about having achieved mastery 7 on a lot of champs. It will also be good for letting people know how many mastery points they have on every mastery 7 champ excluding the top three. Minor and unimportant change but I'm sure many people would love it.
