Default login field

[Havock94]

Hello.

When signing up, we are requested to input both username and email (and both get saved to Enpass).

However on some sites, during login, only email (or username) is asked, and Enpass sometimes fills the wrong value (email instead of username or viceversa) and I have to edit the values manually to be able to login.
Can we specify a default login field to be used on a specific website? E.g. set the username as the default authentication method on a website, and email on another website.
