Yes, you can access the search editor after importing, but there's an important caveat. While you can click on the "Imported Profiles" column > Sources > Last Search and use the blue "Edit Source" button to refine your search further, any changes you make will not affect the results that were already imported.To avoid needing to make changes after import, it's recommended to use the preview button to refine your search criteria before importing. This helps ensure your list is precisely what you need the first time around.
