Combine Target Champions only and Player attack move click

Okay, so I'm trying to get used to using "target champion only", and my only problem is that I can't accurately CLICK on the champion that I'm trying to attack. This is exactly why I use the "player attack move click". For those who don't know, it attacks the enemy nearest to your cursor by clicking on a key instead of aiming with your mouse and clicking. It also prevents you from clicking on the ground in front of your champ. So, Riot, can you do something about this? Combine Target Champions only and Player attack move click. I want this setting so bad. It would really help with my gameplay. Maybe be more versatile on the control options. I main adc, and I want to improve so bad. PLEASE UPVOTE SO RIOT COULD SEE ASDGASKFHLK

My title says combine the two, but I really just want them to work together with two separate keys so I could hold "Target champs only" a

If any of you ADC mains have a GREAT control setting, or even a great way to practice, please tell me about it. Anything that would make kiting and adcing lot easier, I would definitely try.
