»Make Component Glyph« for all masters?

Is it possible to make Glyph > make component glyph work for all masters at once?
As there is no »for all masters« extension by using the opt key, I wonder if there is another way to achieve this.

One idea would be to Make Component Glyph on one master then use this script: https://github.com/mekkablue/Glyphs-Scripts/blob/master/Components/Sync%20Components%20Across%20Masters.py
to propagate that component glyph composition across the remaining layers.


Very good idea, thanks!

This will be in a future version of Glyphs.
