I need a mod for this

I'm looking to make a new survival based mostly around adventure and exploration, but none of the mods that add more structures really work for me. That said, I need a mod (If I knew anything about coding I would do this myself) that allows you to create an NBT structure as normal, then put it into a universal folder. The structures in this folder will generate upon creation of a new world. Does this exist? If so, could you link me to it, and if not, is anyone making it?
