List import - How to not overwrite a particular existing record field
I'm doing a list import from an event booth visits. I have about 100 leads to import and some of these already exist in our db.
I want to import the new 70 leads and also update the existing 30 days. Only field I don't want to update the 'Job title' for the existing 30 leads. Here, I want to retain the value in our db. Is it possible to achieve this? Thanks.
