Does anyone know how/if you can have different custom quick chats for each individual character?

I’ve been trying to see and test if I can put some quick chats on Jeff only but it just equips to all of the heroes instead.

Ive already tried and clicked the ‘Change Hero’ thing and put it on Jeff but it still applies to all of them.

I just need to know if I’m doing something wrong or else I’m gonna start pulling my hair from how long I’ve been trying to get this to work 😭

I’ve tried looking it up on google/safari and I’m not seeing anything related to my problem 💔
