Not that I know of but it was something I was considering, though I would have been attempting to randomize the process a bit by having multiple potential locations with multiple potential encounters per location, and randomized loot.

Though you could somewhat simulate this yourself by downloading the json modules from mod.io and hand placing an exit (unassigned) to allow yourself to export at any time if you wanted. Just as long as that campaign has a central hub, you could allow for exporting anytime you were in that hub pretty easy.

Your idea was actually my preferred method but I haven't messed with the editor so I didn't know if this was possible. Would love to discuss this in more detail with you if possible.
