How to import data via Excel for a multi-select lookup field?

In the Accounts module, I have a multi-select lookup field to the Contacts module. When I import Accounts data via Excel, I want to enter the contact email address (which is used as the identifier) under the column name for the multi-select lookup field. But when I get to the field mapping screen during the data import process in the Accounts module, I don't see the multi-select lookup field name in the list of Zoho CRM fields to map to. How can I import multi-select lookup field data using the Excel data import method?
