They don't appear 'in-game'. SH3 Commander applies them after the patrol is over.
At this time you can go to the 'Edit Patrol Logs' function. You don't have to do anything but look at it once. The next time you are actually in SH3 you can go to that patrol log and it will be complete, including ship names, cargo type and crew numbers.
For a whole lot more names and slightly better organization, use this:
