Daz2Blender question

Safetyman

Everything seems to work perfectly for me except... When I first import a Daz character into Blender the morph sliders are there and working perfectly. When I save the character as a Blender file, close and re-open, all the DTB morph sliders are gone. The shapekeys are intact but most of them are drivers (which drive the missing morph sliders). I can delete the drivers and the shape keys work, but with a lot of morphs that's counter productive.

Is there a way to retain those DTB sliders in a native Blender file without having to re-import the character each time?
