Is it possible to replace the old-style Mk1 coaches in a session with the S&C ones now that they're available as freeware, without going into the session itself and directly deleting and replacing each thing? Like, can you tell Trainz that wherever it finds <kuid:30992:10015> should be, it should just replace it with <kuid2:35412:10064:42>?
