Relocating accessories

Suki.Chan

I' m having trouble editing the location of accessories, because two accessories that I really want to wear both use the same position (the spine). I tried to first attach the necklace to a different location, then manually moving it to the neck, and it worked for the standing pose. However, when I use the sitting animation, the necklace won't be on the neck anymore (it'll be levitating somewhere else). Is there a way to make sure the accessory stays in the same relative place (ie, x distance from the neck, y distance from the shoulders, etc) in all possible poses and animations? Thanks.
