There should be a button that when clicked will apply current accupose settings to every single keyframe selected. This would be extremely useful for MOCAP animations. I could import my MOCAP, convert it to keyframes by right clicking the motion clip in the timeline using the "Sample Motion clip to new layer > Sample all parts optimized" option. Once converted, I could select all keyframes in the motion layer section, set up my accupose settings how i desire, and run it on each individual keyframe automatically.

This would be a game changer for MOCAP imported from Rokoko or Perception Neuron, as it could instantly fix the high shoulders issue when importing MOCAP from these software's and adjust all other parts slightly automatically as well.
