TFT Attack move

I play both TFT and League of legends and use the in-game function that enables attack move on the left click button of the mouse. In TFT however attack moving also works and the little legends walks towards where you click. If I click when buying champions with just left mouse the legend walks towards the bottom of the screen and the screen gets offset. There's no option to disable attack-move on left click in TFT so could it be possible to add this option or disable attack move in TFT entirely?
