How to use layered blend per bone in sequencer?

I am trying to combine 2 animations in sequencer using layered blend per bone but its not working. full body + facial. I used the information on this post using slots to do it but its not working. https://answers.unrealengine.com/que…-slots-in.html

It does work outside sequencer but i want to use it in sequencer. How can i do this?

Did you find an answer?
I want to blend to animation per bone in sequncer (upper bones and lower bones).
I know that it’s can be realized with animBP, animmontage and character’s blueprint, but I’m trying to make that it works in sequencer and on simple skeletal mesh, without creating separate blueprint for it
