Runtime drag bones like in editor

Hey,
I’m trying to recreate the CMD+Right Click drag from the PsyhicAssets editor in Runtime.
(See 08:35 from physics chain/rope in Unreal 4 - YouTube)

I can move the bones in my AnimBP but thaz does not work while physics are activated.
Any Ideas? A function to attach joints to other actors would be awesome.
Cheers
