Customize login/welcome screen

I perform 99.9% of my day to day work with 3 accounts. I use the switch user
functionality on a day to day basis.

I was wondering if anyone knew if it was possible to stick the three icons
on the welcome/login page so I don't have to use the "other user" button all
the time.

In my case I use a local account, a non-priv domain account and my priv
domain admin account.

My kids XP system had this at home and Vista has a little more
functionality...

Thanks for any ideas or suggestion!
