Animate2 stopping body parts snapping back to position

CASINC

Working with G8, I'm trying to add subtle hand movements on top of my animations (sub-tracks), and I can't figure out how to create the animation without forcing the hand to snap back to the original place that animation was created. I want the animation happening at the hand to take place anywhere I move the arm or any other part of the body. The "parts list" doesn't help because the arms are selected by default and I can't click them off. Basically when applying the created aniblock it makes the characters hands snap back to the original translate position, I don't eant that to happen! Any help would be great, thanks.
