To help promote a more interconnected world it would be great if portals could carry a variable that will be used in the destination room to select where the user will spawn.

Example:

A street with multiple buildings with portals leading to other rooms that contain the interiors of those buildings.

When exiting those rooms to come back to the street, it would be ideal if you were spawning not at a default spawn, but actually in front of the representation of the building you were just in.

I think something like this is fundamental for building an interconnected metaverse that is something you can traverse and explore more naturally.

A list of rooms does not provide the same sense of exploration/discovery.
