How to modify character animation inside of unity?

Animation

I have a walk cycle, and instead of creating new animation clips to adjust hip sway for instance, is there another way to do that within Unity? I’d like to be able to adjust the hip sway with a slider. Any suggestions would be appreciated!

There is no built in way to do that in Unity.

Maybe from an asset in the Store perhaps?

I am not aware of such an extension.
