Pose preset either not saving or not loading

I'm attempting to save and reapply a pose for V3 Sherri hair. The hair is not fit to a figure, I select it and File > save as > pose preset. I select the file, then uncheck translation and press Accept to save it. I then select an unposed copy of the hair, then double-click on my saved content thumbnail. Nothing happens. What am I doing wrong? Using 4.8 if it matters.

Nevermind, I was tired yesterday. Of course it doesn't work, because it's not a pose. It's a combination of morphs and a pair of deformers, so I think I can't save it as any kind of preset. It will just have to be a scene subset that I'll use instead of the default hair.
