List all glyphs in a kerning group

Is there a way to do this?

Useful for kerning scripts to print an example kerning pair… since it doesn’t always work to derive a glyph from a kerning group name by cutting off the first 7 glyphs (i.e. @MMK_L_), when the group isn’t named after a reference glyph…? The method I know is cycling through entire font…

Yes, going through the entire font is the only option.
