Default Account selected at Logon screen- Change?

I don't know if a way exists, to be honest. Of all the things to worry about customizing, I can't see this being a top priority, to be honest. Is it really that big of a deal to click on the user icon and login if it shows two or three accounts? The whole point behind the welcome screen was to make it easy for people to log in with multiple accounts present...no more manually typing in usernames to switch.

Thanks for that info too
