Modify chat messages with "?" or "!"#606

I think it’d be cool to add a “?” or “!” to the end of a chat message, perhaps by holding R or L while chatting. The dpad chat system is pretty limited but I think this would be an easy way to make it way more flexible.
For example, you could ask “gotta go?” or “one more?
You could also use it spread a little salt after winning: “that was fun! too good?”

At the very least I think “?” would be very useful, although maybe “!” is not the best other modifier. Maybe a modifier that puts the chat message in quotation marks? Just an idea.

Simple idea but that would add so much more character to Slippi chats lol. Love it.
