Problem with animation on Andriod / iOS : Quaternion Approximation. Is there a way to default this?

I've seen a fix for preventing parts of animated models from disappearing while running on mobile devices due to a setting for the rotation within the animation panel of the Unity Editor: switching from the default of Euler Angles to Euler Angles (Quaternion Approximation). While this is good to know I am trying to find a way to change this as a global default so that I don't have to manually edit this setting on every single animation that produce using the editor's tool.
