I would like to be able to specify a specific instance for the world SDK portal prefab.

Different friendgroups of mine have custom worlds we spawn in using a launch parameter into a specific instance, I would like to "connect" them so we can visit each others shared launch instances without having to use weblinks or navigating menus. It would be much more fun and immersive to be able to just travel through in-world means and build a shared, persistent neighborhood that spans across multiple worlds.
