Currently there is not a way because the import is one way, it can not determine if there is an entry to update. I am planning a revamp. I could add an id column so you could add the entry id to the CSV and instead of adding it’ll update, but it’ll be brute force updating. For example, let’s say you have two addresses in an entry but the CSV only has one … both addresses would be removed and the new one inserted. Would that work?
