Thanks Cariad, I don't think I've ever bought a character, but if that's an accepted way of doing it then I'm glad the option is there.  I just tried it, and I've figured out how to save the Pose only for the eyes (I think), but how am I supposed to get it onto the figure again?

Do I select each eye before applying the Pose, or something else?
I see the eye morph in the Library but I can't find my morph dial for the eyes when brought back on to a fresh figure for testing.
