Sorting Season Highest Grade?

With the addition of seeing your highest grade for every champion in the current season under the "Champions" tab on the client, would it be possible to sort champions based on our highest grade? I'm unsure how exactly it is calculated, but if it isn't exactly quantitatively calculated—such as champion mastery points—then it could be sorted by grade and then alphabetical? I feel that this would be interesting because I'd like to see what champions I've scored all my grades on in order instead of hovering over each champion portrait. I'm not really sure which board this should be in :x
