Layered Animation How to?

Hello,
trying to make a third person shooter from scratch, so I’m working my way through tutorials and documentation.
My current problem is this:
How can I combine those two:

and

I want to use the AimOffset and then use the fire animation for that offset. And how can I “speed up” the offset so that the gun would always point to the middle of my screen?

im fairly certain you would just delete that cached locomotion at the bottom and plug your aim offset into the upperbody slot. if not do another layered blend per bone

thanks, I tried it,
but when I press fire. the AimOffset is gone and the Weapon is back in starting postion
