Or you can easily write your own hierarchy file by following the instructions in the Poser Manuel.

You do not need to pay any extra for Poser's set up tools since they come with the application. Yes you will need to learn how to use them but that can be said of any application. I have a number of video tutorials on my site that run through the process. Often once one is shown what to do in real time it demystifies the task considerably.

Hope that helps.
