How to overcome the awkward animation pose when editing Animations?

I'm using a fully working character from the asset store and want to add Facial Expressions on a second 'Face' Layer using Blendshapes.
My problem is, when working on the Animation in the Animation-Window, the character falls back to some awkward default animation with open mouth. So it is impossible to see the effect of blenshapes. Also I have to readjust the sceneview camera each time.

Any fix to this?
