Smart Pings and Chat Box

I've been playing a lot of solos recently and I came across a problem as I played through my games. Say I blew my lane opponents flash. I would time it and put it into the chat box, but then it would get lost in the messages. This is because smart pings enter messages into the chat box, and the summoner timers get lost in there. Can we either have the smart pings not enter chat box, disappear from the box by themselves after a minute, or have a separate chat box for summoner spell timers? Because it gets really annoying having to retune the timings over and over again everytime it gets replaced by a flurry of pings.
