Saving 2 Passwords in Edge - Same Username

My boss has both a personal login for our retirement account broker and a corporate login because she is the Controller of our company.  The website does not differentiate the corporate login page from the "retail" login page.  Her sole email address is used as the username for both logins, but she has different passwords.  We have successfully saved the logins and passwords in the password manager for Edge, but when you go to the website, only one login shows up.  Is there any way to have both passwords show up as options even though they use the same username?  Thanks in advance for any help you can provide.
