gmail app opening to account list?

I am running 2.2 on HTC Incredible. I have 3 GMail accounts and use the GMail app. I would like to be able to have the account list (the one with all of the accounts and # of unread in each of them) open whenever I hit the Gmail icon but it always seems to go directly into the last account I was accessing, even when there are unread messages in the other accounts.

I could use GMail Unread Count (or something similar) and display all of the accounts separately but I would rather save the desktop space if possible.

I can't seem to find a way to make it open into the account list by default, assuming it is possible. Any help would be greatly appreciated.

Thanks in advance.
