Hi,
I want to import a CSV file of 2800 subscribers. In this file there’s some extra infos who could be used in searches… Is it possible ?
I need a quick response. Thanks by advance for your help and sorry for my bad english.

This is fine for many custom fields, as they only accept one value. However “multiple option (can select many)” fields can contain many values, potentially leading to a situation where multiple values are overwritten by new values imported from your file.
To keep both your old and new data for these fields, use this workaround.
