Its this simple, FSO was designed with a single life, to help immersion.
To help people take it seriously, to prevent exactly this kind of gameing the game.
Its real simple, either fly it with the damage or end your sortie and call it a night.
In my opinion, asking for something in the Wishlist so you don't have to end your FSO sortie is beyond infantile.
It is the way it is for very good reasons. It ain't broke, please stop trying to fix it.
