Data Filter
Campaign Filter
2. Access the filter and add action by selecting:
3. Select "Edit/anonymize data" here.
4. Select which field to edit and what to edit to. You can also choose whether to repeat the action:

5. Finally, select "Execute action".
How you want and use the feature can be very specific, and the video below shows just one example of how to use the feature.
