I know the founders got to pick a lot of names.  Some of them are really, um...nonsense.  I think the practice of letting founders name a system after themselves or their significant other, pet, or unintelligible mumbling was, um, less than ideal.

Nevertheless, I want the following capabilities, and maybe they already exist.

1.  When a dumb system name appears in an existing game, I would like to quickly rename the star and all of its planets.

2.  When an offensively dumb system name appears, I might also want to prevent that damned name from appearing ever again in a future game.

3.  Whether or not both 1 and 2 above can be done, is there a way to make it so that future updates of the game won't regress my changes?

Can anybody advise me?

Thanks!
