- create ure new carrier with sh3com
- still in the harbor or at the startpoint outside port save and leave the current carrier
- delete the just saved game in the menu (its the 2nd in the list)
- relaunch the carrier with a now modified patrol grid with the autosaved game still in port
P.S. I remember about 2 weeks ago disregarding the patrol i got -374 renown in the first patrol from Königsberg. Cant tell if this is a one time event. Since then i manually set a close grid by sh3com and go from there to anywhere i like to engage the enemy.
