Way to keyframe Shapekeys while moving slider?

Heya, so I know how to keyframe shapekeys, but I was wondering if there was an add-on or feature of some sort that would record the position of the slider as I’m moving it, that way my animation could be smoother.

If you turn on the “Auto Keying” button in your timeline (looks like a record button), a keyframe will automatically be inserted each time you change an animated value.

Like autokeying with an animation running? You could probably drive the shapekey from a bone or empty or something and then manipulate that. No need to confirm transformations to get them recorded.
