Different font names (not just files) for different line heights

I'd like to have different line height versions installed at the same time to be able to compare them, but I couldn't install both Medium and Large on Windows since, despite the difference in file name, the font name is identical and installation asks to overwrite.

Maybe add a single letter to the name Monoid XS S L XL (the default medium can be without an extra letter) similar to how horizontal density (Tracking) changes the font name
