Create Intermediate Layers collectively

I have a glyph with few Intermediate Layer. that glyph has been used as a component in many other glyphs.
Do I have to create the same Intermediate layers in all those glyphs to work?
If so, is there a way to create these layers collectively?

You don’t need to do that (any more). You might need the latest cutting edge version.

I am using the latest version (3.0.3)
