I think the easiest way of dealing with this is to create an injection pose that will add my regularly used (non Daz) dials etc to the figure. Would still be good if there was some way to update the figure stored in a pz3 file etc. If Daz created script or exe where you could select the figure you wanted to update, it would be great.
I suppose having to do it manually every so often gives you the chance to leave of the morphs etc that perhaps you don't use so much any more and add newer or better ones.
