Generate structure command

I have a fantastic world, great biomes couple of villages even an ancient portal and some ship wrecks. Big issue for me is there is no illager outpost, rather than start a new world and hope for the best i thought a command might work. Command /generate structure outpost Or indeed taiga church, plains blacksmith etc. These could let you augment a village you find when starting a world so you can focus resources on your builds rather than npc villages, the only thing i want to build for any village is a wall! On applying this command the structure would generate with the entrance/ entry steps on the target block you address when typing the command. The structure would then generate behind it. You could build massive villages quickly, or introduce that one little thig your world is missing.
