Add a comments/notes section when creating new emails and forwarders

As a website admin, I am always creating new email addresses and email forwarders for different reasons.

Sometimes I forgot why I created the email/forwarded and I forget what its being used for.

Would be great if there was a Comment or Notes field that I could enter some info to remind me why I created that email and/or what it's being used for. This field would not be visible to the end user, but only to cPanel admin that can add/modify/delete the emails and forwarders.
