Dodging because of failing to lock in idea

I'm sure this doesn't come up very often anymore but when you have a pretty wide champ pool or your not sure what you want to play and you get to 3 seconds and you're like well.. now i gotta choose anything that's lane viable and click the lock in as quick as i can so i don't dodge. It's frustrating when it happens not just for you but for your teammates a lot. Most of the time if it gets to 1 second i just click anywhere on the champ selection box and click lock in and hope.

i thought maybe a fix for the above senario which would stop the afk senarios still but also give more leighway when panic picking would be if a champ has been highlighted or clicked on or whatever within the last lets say 5 seconds it voids the need to be locked in it will auto lock in like the old system but not if it was like clicked at 18 seconds and the guy afk'd for bathroom l0l.

tldr; if In the last 5 seconds if you highlight a champ without locking in can it auto lock in for you like old system. thanks.
