What if you could select "desired champ" in lobby instead of champ select?

You're only given like 10 seconds to choose your desired champ. If you for some reason could not hit your desired champion you have to hope you can type fast enough to your team to not ban your champion. Sometimes this isn't enough time.

How about, when you choose your role in lobby you can also choose a champion for that role as your desired champion? Maybe even in your "collection" tab.
