Yes, it's an inconvenience. But it is really important? You can't edit them anyway, so ...

This has to be a joke that it still wasn't implemented, I love idea of whole GOG No DRM. I filled multiple "how was your experience with gog?" that go to my mail from time to time but things aren't changing on this platform at all. I wanna support GOG but it could have just come closer to what steam is doing.
