Quote - I don't know of any way to do exactly what you want, except deleting each unwanted morph channel by hand in "Morph Manager 4". 

I do.  Just go to the REM folder for the individual morphs and start clicking on them.
People, it's easy, I do it all the time, and no, it doesn't take away the morphs I want
to keep.  Stop trying to make it so hard and going 50 million other ways when the
solution is right there in Poser and your DAZ files that you bought and paid for already.
Has anyone else actually ever looked at ALL the pose folders you get when you
installed the DAZ morphs packages?
