That's right. Something like that would be pretty useful. But that's exactly why we can't make any definite plans until we know everyone who'll be going with us.

It's up to the Malnosso to get us there, I guess. Initially, everyone was transported to the battlefield at the same time, and at the same place. I don't think they return us to those rooms whenever they feel like it, though - I remember them saying that if we needed assistance, we'd have to call for it via the journals ourselves. Once we're recovered, I'll bet they'll send us back to the battlefield as soon as they can, too.
