Is it possible to use "Button 1" / "MB 1" as Player Move Click?

This is probably the most frustrating thing about this game, in order for me to use Player Move Click, I have to use ALT + MB1 (you are not able to bind MB1 to Player Move Click)

Is there a way I can work around this? I have looked in the input.ini as some other people have mentioned, and I changed evtPlayerMoveClick=[Alt][Button 1] TO evtPlayerMoveClick=[Button 1]

But I have had no luck with this. I can use Player Attack Move Click with MB2, (without having to hold ALT at the same time. But I cannot bind just MB1 for the Player Move Click.

Why is this, and how can I fix this?

Thank you, Jon
