Target Champion Only with attack move click?

So, I have asked the Riot support and they said that a key configuration such as this was currently impossible, but they also told me to post this to the forums so the devs might see this and implement it to the game. I think it is pretty straght forward, if you filter out the ability to hit minions with the "Only Target Champion", and the attack move click makes you attack what is in your range closest to the cursor, this should be the outcome logically. One might has to keep the balance issues in mind if it would be possible to implement this, since it would make kiting much easier, and it might break the game. I don't know, and if you want you can come with ideas of improvement in the comment section.
