Is there a quick way to switch between iTunes accounts in AppleTV? Is there a quick way to switch between iTunes accounts in AppleTV?

The Apple TV Software Update 5.1 supposedly supports 'Save[ing] multiple iTunes accounts and switch quickly between them.'

You can save multiple accounts, but going into settings doesn't seem to be a quick way to switch?
the KB lists the feature ( http://support.apple.com/kb/HT4448 )- but I can't find any other mentions?
The only way to switch is via the account settings.
