Is it possible to use Python or Robofab to mark a set of glyphs ?

I have a complex set of glyphs that I want to mark in a number of fonts to then alter. I know I could to it with a class but I would have to import the class into each font, but with a macro I could simple call it in each font that is opened.

I was thinking something like :

glyphsMark = ['A','C','D','K','1','3','/']

glyphsMark.color = red
