Sorting / Importing Contacts

Can Contacts be sorted?

I just imported my Address Book from Thunderbird and the entries there are stored and displayed as “Last Name, First Name” but the import is showing all names as “First Name Last Name” and I want to sort them by Last Name.

I would have expected the import to show the “File Name” just as it was in TB.

Does this mean that I will need to manually edit each Contact and change the File Name?
