Is there a way to change world generation besides manually editing files?

Is there any way to change more “advanced” world generation settings besides those that appear when you make a new world, besides manually editing files? For example, increase the amount of science labs in a world, or the amount of gun stores, or something. If there isn’t anything in the base game, is there a mod that does this?

No, at least not that I know.

A mod that allows you to change stuff without manually editing files?
That would not really be a mod, more a tool. But I’m also not aware of any that could do that, although I didn’t search for one…

Or do you mean a mod that increases the amount of science labs and gun stores?
