Submarine and Airship Logbook.

I want to suggest an addition to the Airship and Submarine missions, make it similar to the Fishing log to show the possible treasure you can find on each route.
Because it is impossible to keep track of all the items and where to find what.

It's a nice idea I like, especially if the loot remains hidden until retrieved for the first time. It leaves that sense of mystery about what else could be found there for some time.

This would be so helpful for reference without relying on external trackers.
