How can I attack move click to kite while only targeting champs?

So the attack move click is by default "a" then click. (I use shift click when kiting)
There is also the default key "tilde (~)" that will allow to target only champions.
The main problem is that when kiting an enemy champions and if there is an enemy minions closer to me than the enemy champions, I would start attacking the minion rather than the champions (when using "attack move click")
So is there any key binding to allow for attacking move click to kite while only targeting champs? If not, is there any "trick" that would allow for such move?
NB: I found some kind of answer on reddit but I don't understand it, and I'm not sure it is actually a correct answer.
