How to have separate controller layouts for each game in Heroic game launcher?

Hi everyone!

I was wondering if someone had found a way to have a separate controller layout for each GOG games in Heroic game launcher? Even better, a way to use community layouts found on Steam?

Apparently you could do this by launching the games from Steam Os as non-steam games but I guess I wouldn’t get the GOG achievements by doing that.

I know it’s stupid but I care about achievements 😅
