Import Marketing List

Import Marketing List

Initially when I am building a CRM, I import a csv file containing company information.  I then build a separate csv file with the names of people from the companies I just imported.  The csv files of people has the same company name.  Is there a way to import the people and automatically add them to the contacts for the correct company?  For example, company x has a list of 10 people with different titles, phone numbers, etc.  I want them to show up as contact for company x using a bulk import.
Thanks.
