Attack move and target champions only

It would be really nice if you were unable to auto-attack minions when you hold down the "target champions only" button and A-move. For those who don't know, "target champions only" makes you unable to choose a non-champion unit when you auto or cast spells, but with A-move you can attack a target you don't choose by targeting the ground, attacking the closest unit. I feel like Riot should add a special interaction where targeting the ground with A-move when holding down TCO makes you attack the nearest champion instead of just the nearest unit.
