username update for servers with nitro

so i was thinking that you can change your username in servers with nitro! like you can add a display name still but you can also change your username for the server like if your username is “ilovegamesss1” on your actually profile in the server you can change it to like “iminlovewithgamess1” it would be really cool if discord added that and it would be fun too! like its just a suggestion but i would really love to this see on discord
