To add Aggregation, open the relevant tab and click icon. Here you will need to adjust:

- The field you want to aggregate by
- Prefix — the name for the aggregation shown to the end user
- Position of the final result and display option

Note that Aggregation is calculated for each Group of the Library separately.
