One primary issue here is simplicity.  Many of us who have gravitated to VSS and have become dedicated users have, in essence, devoted considerable time and effort to learn this process correctly.  Many Poser users expect to hit the ground running with out-of-the box software without bothering to learn the essentials.  And it shows in a considerable number of God awful renders displayed in the gallery.  The learning curve is not steep but mastery will take considerably time.  Heck, mention mathematics and material room and many users run for the hills.  Yes, it would be great to have such a feature built into Poser but you would need to train a core tech support knowledgeable in just this application alone.  It is becoming more apparent that we will become the tutors for every new generation of Poser neophyte, free of charge.
