Hello @Bristolyc ,
Anytime you import a file into your CTCT account, our system will treat that as the most up-to-date info - including for re-imports. Therefore, if you're wanting to not have your file import overwrite the information in place for already-imported contacts, you'll need to make sure they're not in that file.
One potential way this can easier is if you:
Export your current CTCT contacts and all info
Import the new list of contacts
Import the exported CTCT contacts to overwrite that new list's changes to the pre-existing contacts
