Depending on what you are looking for, there are various flavors of Injection pose programs around that may suit your need.  The DAZ programs (Yes, they have more than one) concentrate heavily on their millennium figures and work rather well.  I am not familiar with any script that would help create the files in Poser 7, but I can recommend Dimenion3D's tool collection which contain excellent inj/rem pose programs.  They are easy to use and yield excellent results.  I even used 1 program to create Inj/rem pose for an M3 bodysuit featured in my Superman avatar.  It worked better than I thought after searching everywhere for the right program.  The link is below:
