If you know what to change in your career cfg files and (I assume) your crew cfg files, you can award or take away medals as you see fit, outside both the game and Commander. Both programs will then read the edited cfg files and show your updated medals/badges accordingly.
I know this because the game has awarded me the front clasp after my last two completed patrols and I went into my kaleun's cfg files and removed it. Since I'm still playing in 1940 nobody on my boat should be getting it, lol. It didn't exist until 1944.
Sorry I can't remember offhand which line I edited. But there's a thread here somewhere or in the Mods forum where someone listed what line corresponds to which medal. When a medal is awarded the value on that line changes from -1 to a positive value. I just go in and change it back to -1 for the front clasp, and then reopen SH3 Commander and look at my personnel file to make sure it shows the right medals/badges.
If I live past May 15 1944 I'll happily accept the front clasp, but not until then.
