Editing an existing data view
Perform this procedure to edit a personalization (data view) that has already been created either by yourself of a user.
Note: You can create a new data view from an existing one. You might do this, for
example, if an existing data view has most but not all the customizations you need.
Open the existing personalization and then use the Save As option to save it under a
new name. Then open the newly created data view to make the rest of the
customizations you need.
