Can I update Contact Emails as Opted-Out via Import?

I have a list of Contact email addresses from our Email Marketing System (MailChimp) and want to set their SugarCRM Email Status based on MailChimp status (e.g. MailChimp "Unsubscribe" = SugarCRM Contact Email Opted-Out, MailChi mp "Hard Bounce" = SugarCRM ?). Is this possible to do via Import or other means? I am aware that the SugarChimp service / add-on can perform this sync, but I'm not ready for that yet.
