A lot of Poser functionality has been exposed to the user and may be manipulated using Python scripting. You can write your own scripts.

Over the years I've written one or two, see this page for my full list.

The Poser Tool Box and Pocket Knife are listed there.

If you go to the Poser help menu you'll be able to bring up the Poser Python manual. If you find that to be somewhat rudimentary you may be interested in the one that I wrote.
