Is there a fast way to keyframe everything in an animation?

I have a model with over 60 bones, and I am trying to make an idle animation that doesn't keep the rotations/transforms of other animations, and the way I found to do that is to keyframe everything, but it is extremely slow for me to have to go through all the bones twice and record them with no change in rotation or transform.

Is there a faster way to keyframe everything?
