==================
Good morning, my question today is if i can overwrite some attributes of a participants using a CSV file, for example, i want to change the attribute field "Resend email" for "yes" to "no", on multiple users (I know the massive edit feature, but im talking to select and click more than 200 participants, i want to avoid that), i can do it if before y delete completely the database and import all again with the changes, but my question is if i can do that without deleting the participants before, i try to do it but Limesurvey say that is no possible to do it because of the TOKEN is duplicated.
¿There is a way to change an attribute value for multiple participants without deleting the participants before?
