There's the "apply marker" system in the gallery and there's also Maggie's "marker removal" service which should show the visuals of how your player character looks.
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!
