Easily add contact group members from emails' senders or recipients in Outlook

Normally, we can copy a sender or a recipient from an email, and then add it as a contact group member with Add Members > From Address Book, and it seems no way to add multiple emails' multiple senders or recipients into a contact group in bulk.
