I know in poser you're able to lock hand parts and figures.. Is there some way you can lock other single body parts beside just hands? For instance.. say im working on a pose.. and have the top half of the body looking just the way I want it.. am I able to lock the upper body parts.. so i can then work on posing the legs or something.. without risk of somehow messing up the part of the pose that im happy with?? Any help or suggestions appreciated
