As a rule, if the majority of users adding contacts upload a new list, THAT should be the first option shown - NOT a select from. As with all things logic, the most frequent use should be at the top. Now, if that's already the case, and this user is just not a part of the mass, then I understand. Bigger picture, check out Mail Chimp and it's logic. It's easier than CC. Just giving human user feedback. Thanks.
