It would be nice when you pack and go project, if it contains frame generated parts it will also copy over the original frame generator assembly along with the frame and skeleton regardless if the frame generator assembly is directly referenced or not. I often will use a "frame generator only" assembly to save time modeling and then use those generated members to create sub-assemblies. I find this to run better then creating a separate frame generator for each sub-assembly I need. However when I go to Pack and Go the project it leaves behind that "parent" frame generator assembly along with its frame and skeleton and I have to manually copy those over.
