I'm using dataloader.io to import a large number of records (60K+) into a custom object with a large set of fields. I'm testing using a small file first (10 rows), but I plan to do a large import next with the remaining data. There are two different files, but the column headers are exactly the same. When I go back to my saved import task in dataloader now and change the csv file to be imported, my field mappings get trashed.
Is there a way to save my field mapping settings from the first test import so that I don't have to reset the field mappings when I do the remaining import?
