Is there a way to automatically capture/record email address in custom fields?

When creating new accounts, I often have to manually create and populate a custom field for the email address used for account registration. It’s also fairly common for Bitwarden to automatically capture the email address as the username, so I have to manually swap those around, too.

Is there a way I can set an ‘email’ custom field to be a standard part of all my saved item records and for Bitwarden to attempt to automatically recognise email addresses and capture them in that custom field?
