Can movement (Default right click) be changed to left click?

Title says it; I want to still be able to move using the left click and want my attack to be right click. I just feel like I could control my movement and avoid projectiles much more reliably if my movement were on my left click and would feel better if my movement was separate from my attacks. I know you can control-right click to attack, but I would rather move with my left clicks and have the two movements separate.
