Toggle "Orient Rotation to Movement"?

Can this option be toggled in game? I want to make it to where its on when moving in any direction but backwards, (i.e. I want my character to be facing away from the camera when walking backwards)

Or Should I just leave it off all the time and adjust my meshes rotation manually?

If the ladder, does anyone have any advice on how to make smooth rotations without the aid of the movement components automatic orientation? Some kind of loop that gradually adjusts the meshes rotation no?
