As far a I'm aware this isn't possible, at least not from inside the game. The closest thing I can find is here about changing things in the game files themselves: https://www.vintagestory.at/forums/topic/3849-option-to-change-default-world-gen-settings/ but this looks like it was a couple versions ago, so it may be a bit different. Also it obviously requires manipulating the files which is a hassle and a little scary imo, lol. It would definitely be a very useful feature though!
