Auto face option disabled just for healing spells


Would it be possible to exclude healing spells from auto facing target, when the auto face option is enabled? When I heal, I don't want to auto face the target because I want to be free to move knowing that my position doesn't change if I don't actually move at all, but when I tank or dps I do want to automatically face targets. Now I have to enable and disable the option every time I change role, but I wonder if I could avoid that.
