Removing Glyph from Master

I’m wondering if there is a way to remove a Glyph from a Master rather than the entire font. Is this possible?

What are you trying to do?

In my current Glyphs file I have 4 proportional Masters and 4 mono-space. I have ligatures for the proportional, but don’t want to have ligatures for the mono-space. Is there a way to export the proportional masters with the ligatures glyphs but not on the Mono masters?

EDIT Or perhaps this is poor practice and instead I should separate them into two different files, that would solve my issue. Just wondered if what I asked for is possible

If it is static fonts, you can use a Remove Glyphs parameter.
