I have a very large group of objects placed in a .world. It's a town on a pier. Is there any way to copy or save all of these objects together the way they are positioned so that they can be used in another .world identically? It took me weeks to place each object and it would be insanely tedious to do it again.

If there is no way to do so, might this be a possible feature to be included in the future?

groupping objects is on the roadmap

for now you could just save your world with city as a different world.

ok cool, thanks!
