Only posting this here because there isn't a "suggestion" forum and this is the next best thing. I hope Iceborne adds more Manual Shoutouts (the ones that display your customized message for people who speak the same language, and a basic one for foreign-language speakers, or at least those who have their game's language set to something else).

In particular there should be messages for breaking monster parts like "Someone cut the tail please" or "Break the head please".
