It doesn't super matter if you can or not, I'm just curious if it's possible to. Whether in game or if there's a spot in the files you can change it. Not sure if it's something that's one file that gets read every time someone says your name, or if it gets individually added to each dialog after you input it.
I was just wondering because I've been trying to find ways to try out different names for myself irl without asking other people and this seemed like a fun way lol
