I saw someone else post this question but they never answered the follow up
questions!

I am importing a list of names and addresses into a contact folder. The
list is a CSV file that includes company names. I have my default "file as"
set for Company (Last name, first name) but once the list is imported, they
show up as Last Name, First Name. I have well over 2000 names and I'd rather
not have to go one by one updating the contacts to my prefered display
settings.

Is there a way to import these using my default "file as" settings?
