Add Account Manger as a synchronised field in Mailchimp. Merged

When I export a report from Mailchimp to see who has opened/clicked through on mailers, I also see synced CRM data such as CRM Contact Role, CRM Company Name, CRM Industry, CRM RFM Segment. I woiuld like to add CRM Account Manager to that data. This will allow me to report mailers by account manager for follow up.
