Not yet. This is actually a feature a started during the work on 2.0, but it remains unfinished. The ability to import cells, screens, banners, etc, from another layout... will eventually get there. For now, you'll have to duplicate the items manually.
To learn more about creating a layout, all I can really suggest is to consult the user gude and take a look at the various included layouts, and those that others have shared to see how things are done. Knowing/learning HTML is a big plus as well.
