Link worlds (world+nether adventures)

[Dritz]

Requesting a feature to link two worlds, for example a world and a nether, to reset at the same time, as well as share a delay / reset timer (so playing in the Nether won't reset the overworld, and vice versa)

[Phlarx]

Even an implicit linking by name (world is linked to world_nether) rather than explicit linking (world is linked to spaceworld) would be immensely helpful.

I agree that this is needed as many adventure maps include a portion of it in the nether. Is there a way to do this allready?
