I'd like to add custom symbols for my nicklist instead of the standard server sent ones like @%&+ but I can't seem to find anything about doing this. The closest I've been is using /cline to change the nick colors, but that's not exactly what I'm looking for.

If I manage to do this though, let's say I change @Nillen to !Nillen, would I still be able to use menu nicklist to target the user in both channel messages and the actual nicklist?

Nillens @ irc.twitch.tv
Nillen @ irc.rizon.net
