"I  had this info before, but now have the same question.  If the dials are spun to create a character out of existing morphs, how can that be saved so I can apply it to the base character in the future?"

I am attempting to find a post at Daz that explained this exactly.  I've done it myself, but know I would fail miserably in trying to explain.  In a nutshell, once you have the morph dialed, you add it to a Pose folder using the "+" (Add to Library).  There is an option (Select subset) to click exactly what you want to be saved for the morph.  I have saved full inj's (for a full character) and head inj's (for only the head) using this method and I've had no problem in applying them later.  

As far as spawning the remove files, etc., this I have yet to attempt, even though I have svdl's script.
