How to use BW to set up email accounts

How can I use BW to store and autofill all the information for my IMAP email accounts. Do I just create custom fields for:
Manual setup boolean?
IMAP account boolean?
Email address
User name
IMAP server
Security type
SMTP server
Security type
Port (what to do for 2 fields with the same title?)
Require authentication to send emails (Boolean?)

You could of course do so, but, personally, I would prefer using the browser’s extension to save the basics credentials directly form the website of your email provider, then add the rest of the information (non-persona) directly to the notes section of that Bitwarden’s item.
