A more flexible approach would be to use the Poser API to duplicate the master object and apply to each duplicate the transform of one of the place holder props. This would also have the advantage of being able to take pose and morph data from random frames if the master object is animated to create a more varied scene (eg marching band horn section from a single figure). The problem with this approach is managing the fake instances can become a bit of a chore. What I think is an advantage of the method above is its ability to manage the fake instances (the figure parts) as one.
