add member to multiple glyphs in one step [COLR opentype font]

Dear All,
I am learning fontcreator (30 days evaluation period) and i want to create an COLR font like The Bungee font:
https://djr.com/assets/bungee/images/bungee-color.gif

I understood that i need to compose each individual glyph (A B C …) with 2 members if i want 2 colors.

So i have copied all glyphs (A B C …) to A.001 B.001 C.001 … and i modified them the way i want with the transform tool script.

Is there a way (using transform tools ?) to add A.001 as a member of A, B.001 for B, C.001 for C … in a single step
? Because doing this for all 460 needed glyphs will be really painfull.

I am trying with the transform tools to do so … but without success so far.
Any help appreciated.
Thanks :smiley:

There is currently no easy way to make it work for a selection of glyphs, but the next upcoming update will allow you to copy and paste glyphs from the Glyph Overview as Color Glyph members into a Glyph panel if the color mode is set to COLR.
