Make chat only show SS timers?

Not saying have it record enemy SS timers for you, like make the chat only show personal notes. So no chat, no pings, just the stuff you write. So that I can just write "graves f 13:15" "Tristana f 15:10" for example, and have those things be the only thing that shows in my chat. I feel it would be a much easier way for myself to keep track of that stuff. Since let's be honest, we don't remember that stuff much unless someone else is saying it as you are ganking. I'd like to know if I can already do this, or if someone knows of a plugin/mod to do that.
