How 2 objects play their animations simultaneously from one controller

I've got this man and the controller is attached to parent. It consists of different objects as I want to animate them independently and play animations of wings, head, claws WHEN-EVER I want no matter what is being animated now, so imagine that every part of IB-84 can be animated at the same time. But no. One animation stops when another awakes and it doesn't even matter than these animations animate different objects. But anyway controller cannot handle more than one animation at a time. Ofc you can say just have controller for every of your objects but what if I want to use my anims in only one controller? hhhelp

 

I wish I can help but I am on here looking for an answer to this as well. I want to play one animation on top of another simultaneously as they are the same object. Have you found out how to do this yet? The multiple controllers is where I end up too but that seems silly and using more resources than needed. Thanks
