[Plugin: nextgen-gallery] Adding a Gallery to More than One Album

I forgot to add the plugin tag in my title, so I’m reposting my question.
I am looking for a way to add a gallery to more than one album. I’m creating a site for an artist, and some of his work fits under more than one listing. I have albums set up for Realism, Interpretive, Functional Art and Miniatures. I was thinking I could create two galleries with the same content, then placing one gallery in each album, but was wondering if there would be an easier way to do this. I don’t have a problem with getting into the php files if the instructions are clear.
Thanks,
Lori
