¿easing in/out the animation of multiple bones at once?

Hi, there is some way to edit the f-curves control nodes of multiple bones at once? Select and edit multiple control points at graph editor is tedious.
I´d like to edit only one curve to control a entire pose easing. Is there any work around to dosome similar? Thanks.

you could use NLA editor to animate evaluation > strip time for the entire action, it works like a time remap, keep a copy of your file just in case…? other sometimes useful thing is setting fcurves pivot to ‘individual center’ when editing many curves
