You can also save your first scene to the Scene Library, in Poser 9 / 2012, then load from there into a new scene.

Maybe more the way to go if you had a part of a scene that you planned to re-use more regularly... e.g. an environment with other figures or props, and lights perhaps, arranged in it... and it was useful to have that part-scene in the Library...

...don't think it'd be worth saving anything into that Scene Library unless you planned to use it more than once?
