Transfer shape changes to actor in a series

Series of 10 pictures, then I realize a much better shape set for one, eye shape, different browes, leg shape etc; a handful of tweals.

Now these tweaks are in picture 10. How do I get these changes onto the other 9 without having to reload, reshape, re-pose the other 9? So, like "apply to existing characters", but that deosn't work from a saved Scene Subset of the character.
