Dynamic Que Lock in Alert

Can we please get some sort of alert, either by sound or text or both, to remind/instruct players who haven't locked in yet that they need to lock in? Like if we get to 5 seconds with no lock in and the game reminds you in a very attention grabbing way? My team of 4 just had 5 fails in a row because people didn't lock in their bans and champ picks. They selected them, but never locked in. It's getting old. [zombie-brand-clap] [slayer-jinx-unamused] [zombie-brand-facepalm]
