Can We Set "Attack Move" to Quick Cast with Indicator?

Howdy,

After experimenting and researching, it does not appear possible to Quick Cast the Attack Move command (deault bound to A). Of course, one can use the Attack Move Click command (default bound to Shift + R MB), but that does not allow the player to utilize the range indicator. I would love to have the option for Attack Move to be Quick Cast with Indicator.

To clarify, I want Attack Move (e.g., "A") to be able to function the same way that a primary skill (e.g., Q) does when set to Quick Cast with Indicator, not requiring a subsequent mouse click but retaining the option to keep the key held down in order to check range.

So my question is this: Does anyone know whether Riot has plans to implement this Quick Cast Attack move with Indicator function? If not, might it be possible to implement it?

P.S. If I'm a dunce and this function already exists, please let me know -- I will provide you, as a token of my gratitude, every cattle in my livestock (approximately 0 total).
