Time Options - TZ picker in v7

How do I make the TZ picker available on the main dashboard page, ie next to the time range picker. I just upgraded (on a test box) and all, so I am probably missing it, but it looks like I need to go to either dashboard settings (as admin) or user settings (as non admin) and change it there. So if I have 6 timezones in my data (and sadly I do). I would need to this every time … hence my question about getting the TZ picker on the main dashboard page. Thanks.
