Outlook Email 2 & Email 3?

Outlook Email 2 & Email 3?

I've noticed that I had a few duplicates in Outlook, which had in turn duplicated themselves in Zoho (Since I had Zoho sync with outlook). However, some of the contacts had 2 or 3 different email addresses, and there's no eloquent way to do this. Can I add additional "Custom Fields" to migrate the Outlook "Email 2" and "Email 3"?
