I am looking for a way to show a Company, as a LEAD NAME.  We are a B2B company, and 90% of our LEADS are businesses...not individuals.  We have a list of companies, with no contacts...I could potentially trick Zoho by populating the LAST NAME field with the Company name.  I have another list with Company and contact from a trade show.  The contact is not necessarily the person we need to communicate with, but is our starting point.  How can I have Zoho import the list, with the Company as the LEAD NAME, and still maintain the contact information?
