We need to import data stored in CSV into Zoho Creator, and have built into Zoho Creator multi-form relationships. How do we get that to work?

For example, we have a form for adding Employees, and a form for adding Companies. The Employee form has you select a Company from a drop down that links to Companies.

Then, we have a CSV file of Employees, with a "Company" column that lists the company as a string. How do we import that CSV file into the Employees database in Zoho Creator to where it will know to link to the appropriate Company?

Thanks!
