Currently, it's not possible to customize the fields that by default show up in the Screening Room for RV Submit Tool. It would be great if these were made customizable. For instance, set which fields are required in addition to the other changes (like changing the required fields, updating the labels on fields as you can do in Shotgun, etc.).
