Add missing glyphs with "Add Other Font"

Glyphs

Hey,

Could it be possible to import missing glyphs when using the “Add Other Font” feature? For example, if my source file is in Latin, and the other font I’m adding has Cyrillic glyphs, would it be possible to generate the missing Cyrillic glyphs in the source file during the import process?

The “Add Other Font” is meant to import another master e.g. if you merge a Regular and Bold styles into one file.
You need to either copy paste the cyrillic glyphs or use the “Import Font” custom parameter.
