I have a file that I will be uploading into Marketo on a daily basis. Some of the records in this file will already be in Marketo. The records in the file that are also in Marketo, I want their data to be updated, but I do not want the records in the file that are not in Marketo to be added.
I looked at the import settings, and didn't see any selection that I could make to achieve this. Is it possible?
Thanks in advance.
