Add optional label to identities

[rufusz]

Would like to request following feature: have multiple signatures for a single identity.

Scenario: when using a shared mailbox by multiple employees, like office@xyzcompany.com, we would like to select different signatures based on who is sending the email. This is possible only by creating multiple identities, but the problem is that display name should be the same in all sent mails "XYZ Company" to look professional. If I create multiple identities with the same display name, it's hard to select it from the compose dropdown because they look identical.

Alternative solution would be to have a description field (optional) for the identities, next to the Display Name, and use the description fields in the compose dropdown.
