Is it possible to align Windows 7 taskbar buttons with the button above it when the taskbar is >= 2 rows in height?

The default behavior is to begin "staggering" the buttons when too many windows are open.

I've tried many utilities and registry hacks, including 7+ Taskbar Tweaker, but no love. It's quite possible the correct answer to my question is, "No it's not possible," but you never know until you ask, right?

See attached screenshot for clarification of what I'm talking about.

P.S. Yes, I'm OCD. ;)
