Surveys change over time - we all know that! In Presto, there isn't any versioning of questions, so this can be a little tricky. You can always add new answer options to a question, but Presto won't allow you to delete an answer option if there's data associated with it. As a result, to "version" out an answer option, you'd probably have to make a new copy of the survey.
Now Presto lets you deactivate an answer option! This preserves all historical data for that answer option, but hides it from evaluators.
Deactivating an answer option is done through a database setting, so if you need an answer option deactivated, please contact our support department at firstname.lastname@example.org.
