I like the MailChimp integration very much. I am building a Dynamics CRM - MailChimp integration Flow. But I would love to have that work two way. With the current MailChimp triggers and actions, it is only possible to create a Flow that adds a member to a MailChimp list when "something" (new contact for example) has been triggered in Dynamics CRM. I'd like to update the CRM Record / Contact / etc. too when someone unsubscribes from a List in MailChimp.
