A pose can be used to add geometry to a scene via a geometry insertion pose.  I don't think it can add the actor into which the geometry is to be inserted, however.  It has to be inserted into an existing actor in the scene.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
