The way the TARDIS automatically chooses a location for its interior is convenient... but sometimes causes problems.
On some maps it can spawn inside a teleport trigger meant to keep players out of a secret area, or a location that reacts to any props spawned in it, or just someplace with a view of so much of the map that it's laggy when looking in certain directions.

I have a couple of ideas that would help.

A: The ability to create box volumes that get saved per-map like destinations, and tell the TARDIS to either prioritize spawning interiors there or avoid spawning them there unless there's no room anywhere else. These could even be included by mappers if they want to make a dedicated box somewhere for TARDIS interiors.

B: An advanced option maybe somewhere in the TARDIS menu, to manually place the interior with a preview like the manual destination mode. Ideally this would be done without needing to enter the TARDIS, either when a new TARDIS is spawned or the first time the player presses use on it.
