Copying parameters without losing the keyframes

[dusky jolt]

I REALLLY don't wanna rig everything for the breathing parameter so I made a physics group for breathe and put everything I wanted to move in it but that messes up the other physics groups for example the wings and the hair y. I want to copy all the parameters I want to move but it never copies the keyframes with it

why don't you just add breath as an input to the already existing physics groups?
