Riot, can we have sort by skins?

I own a lot of champs and have skins for most of my favorites but with gifts from friends I sometimes forget what champs I have skins for. Just wondering if we could get a sort option in our profile's champion list to show what champs we have or don't have skins for. Would help a lot when deciding what skin I would like to get next (since I try not to get multiple skins for the same champ.)
