Unit Sounds

I've been reading through posts and it seems that it's not possible...

I'd like to replace the sounds of a unit (What, Yes, Pissed, exc...) with my own. It was said you could by installing blink by Cookie. But I had to modify a file in order to modify the sound variable but it still didn't work. (My thrown in Marine units never showed up, either...) And I wanted it to so the sounds would be in the map, so everyone who played it could hear them without editing anything themselves.

I know this has been a topic that everyone has been talking about, but if anyone has found out anything new about it I would greatly appreciate it. Thanks!
