Copying MetaHuman bone transforms to a separate skeletal mesh AnimBP

Hey everyone, I’m making a custom Metahuman which has a skeletal mesh hair instead of the normal grooms. The skeletal mesh hair is attached via a socket in the character blueprint and has its own animbp and unique skeleton different from the metahuman’s. I am trying to get a specific bone from the hair skeletal mesh to follow the transforms of a specific bone (the clavicle bone) on the MetaHuman it is attached to during sequencer animation. In the hair animbp, I added a copy bone node, but the source bone drop down menu only includes the hair’s bones, but I want the source to be the clavicle bone from the metahuman. I tried a workaround by using variables but I can’t figure out how to use and cross reference the same variables in separate animation Blueprints which exist within the same character blueprint. I have been pulling my hair trying to figure this out, but to be fair I am pretty inexperienced when it comes to blueprints. I would greatly appreciate any help. Please be patient with me and explain what I need to do in clear steps :folded_hands:
