Delete all kerning groups but maintain kern values

Hello, I messed up with some groups with a script font and some glyphs are not so equal so grouping kerning is resulting some mess. Basically when fix some pairs, others broke and so on. Silly thing so I need to manually kern each pair. Is there any way (or script) to remove groups and keep the actual kerning?

thanks

There is a script by @TimAhrens in his Freemix Tools called expand kerning (opposite of compress) that does exactly that:

The script isn’t working, at least in last cutting edge version of Glyphs. When tried, wheel keeps rolling and I have to force quit the app :___( ping @TimAhrens

It is probably best to open a GitHub issue.
