please, I need feature/trick as such too. Not only for backup but for working with multiple profiles as well, I have for example my notification tiles set up in a specific way, but only on my main profile. I use about 5 profiles total, 3 on weekly basis and I didn't find the time to tweak all of them to my liking, so I use the non-main drivers kinda vanilla and it just is not really comfortable.
It would be great to be able to export my settings and them tweak them on individual basis depending on the aim of the profile reather than having to tweak each profile separately from zero.
