Import contacts into Zoho mail from CSV file

Import contacts into Zoho mail from CSV file

Hi. I am new to Zoho mail.  I'm trying to import contacts form a CSV file.  I have many fields - more than are listed in the import contacts screen.  For example, I have several phone numbers for each contact (work, home, mobile, fax).  I see only one phone field on the Zoho screen.  Is there a way to ADD more fields?  Thanks.
