Do what geep says, it's by far the easiest way. If you have stuff on the figure like clothes and hair etc. you will get a message about saving as a group. Say yes and then it will be saved complete. I do it this way all the time when doing a story line for instance. Make and clothe the character and then save complete to the library to be used as and when I please and the when I've finished with it just click on the "negative" mark and it's gone!

Injustice will be avenged.
