If you haven't already do check out the latest version of the game, v1.04. We've implemented something a little similar to that suggestion.
Maybe add a player character codex entry that shows the current character configuration like the in Mission status?
Sorry if im overstepping for suggesting that, i just think that those options are a bit limiting?
Plus, you could do fun notes with the PC and maggs?
Ah, I just found what you mean with the marker removal service. Sorry for the troubles!
