Mood stances

I just had a thought.....would it be possible to have mood stances or mood facial expressions on/off?


for example:

If you are feeling happy, could we incorporate a smile on/off.
If you are meh, just the neutral face we have already.

The glitch where you could run about with your hands open made me wonder why cant we have an on/off emotions switch.

First time of actually asking for an animation lock haha.

Prime example of how an animation reverts back to a moody face.
