## Additional Information

- If a Dimension is renamed to a Dimension name that already exists, the Dimension will not be recognized by Databox. To aggregate multiple Dimension values, it is recommended that you use [Data Calculations](/overview-calculated-metrics) to add together the unique Dimensions and produce a new Calculated Metric.
- For Agencies: Excluded and renamed Dimensions will be retained when Custom Metric is used on a Databoard and copied to a Client Account.
