Use Artwork from other puppet and Save as

Hi.

Is it possible to open an existing puppet (or template with scene), edit the artwork in its Photoshop/Illustrator artwork file but then save the artwork to another file so as not to alter the existing file that belongs to the other, still needed puppet?

I'd like to start with an existing puppet I've created and use it as a template for another puppet without destroyling the originial puppet artwork. 

Character Animator definitely has a steep learning curve!

Thanks so much.

Daniel.
