multiple urls

My bank has a two screen login. when I open my banks main page it asks for the user name. I use 1 password 4 to autofill the user name. then I must click on "login" to advance to the second screen where it asks for the password where I again use 1password 4 to autofill the password. I thought that by editing the 1 password 4 login screen by adding the second url, it would automatically advance to the second screen. It doesn't; so am I missing something, or can the program be set to advance to automatically open both screens without manually advancing from the first screen to the second?
