You're talking about in the shader room where you can copy/paste or drag drop an individual shader and all the channels are there? If so this I know. I am trying to avoid applying all textures that I already have in the file with the default shaded object all individually all over again.Otherwise it puts a serious dent in using native support very practically.It will take less time to redo all those shaders than rig a new skeleton probably, but really makes little practical sense.

No need to think outside the box....
