Copy theme function

I have gallery configured with your plugin. Idea of the themes is really good, only one thing it’s themes configuration. When i setup my first gallery and slideshow after that I had only one theme created for every of this item.
Later I decide to create few different sliders view and gallery layouts, but based on source themes which was create for a first gallery and first slideshow. I didn’t find copy theme functionality, which would be really helpful for configuration of the gallery items in the case if default themes have a lot of changes (if you compare with default theme). Do you have such plans or maybe you can suggest some gallery trick to make it’s possible ?
