Can't you use 2 separate morph folder? I remember my G8F loading time was like 1-2 min long and I didn't want to remove my characters/morphs. Then I read about the use of 2 separate morph folder. One is just the basic morph I use mostly and the second one is filled with all my char/morphs.
By default, only the basic morph folder directory is specified in Daz, so it can't find all other morphs. If I need other char/morph, I can just second morph directory in daz.
