Multi-kill timer?

Would it be possible to put a little timer somewhere when you get a multikill that shows how much time you have left before it expires? It's kinda stressful to have a quadra kill and not have any idea how much time you have left before the streak runs out and you cant get a pentakill anymore.

It's not the biggest thing in the world but I feel like it would be a nice addition that doesnt seem very hard to add.
