Add more techno subgenre

Hello. Compared to house, I think there are fewer subgenres for techno. I DJ stream techno, but techno is the only genre that fits, so I can't use the other two genres. Also, because techno is such a broad genre, various types of techno are mixed together on one channel, and I can't tell what it sounds like without checking the stream. Therefore, I would like you to add genres like "minimal", "hard", and "underground".
