- Create a multiple relation column that matches the Publisher with itself.
- Create a rollup column, target it at the multiple relation column, and select Sum-\>Impressions (or sum-\>Media Costs)

To create something you can use as a filter:

- Use a single value column to take the first RowID from the multiple relation
- Create an if-then-else column and apply the following condition:  
– If RowID is single value RowID, then `true`
- Use the if-then-else column as a collection filter (only show rows where it is checked)
