Shapekeys for Curve hair

As far as I am aware, there's no such feature. We need to make duplicates and keep them as backups if we wanna store that "style". This is a bit annoying when you're posing characters for example and then grooming the hair for the specific pose. God forbid you forget to duplicate or save and that style is gone forever.

The best solution for this that I can think of is adding a shapekey feature like meshes and lattices have. It would be a very helpful addition. It's kind of weird that it's not a feature in the first place tbh.
