Button in Chat plugin to ban by e-mail?

In a chat plugin admin/moderator can ban chatting user and there's a button for this right in a chat window. This is a ban over IP. There is an option to ban users by e-mail in back-end but there's no such button in a chat.

Is it possible to add "ban by email" button directly to the chat window so instead of having to copy a user e-mail, then go to back-end and add to blacklist there, an admit or moderator could simply click "ban" next to the user message? Just like it currently works with bans over IP?
