I've shown how to save leg poses. But the process is the same for the upper body or just hand poses.  Just make sure you are selecting only the body parts that are affected by the pose.

For arms, you would select the collar, shoulder, forearm, the hands and fingers.

For hand poses you would select  just the hands and fingers.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
