We've just added two additional dimensions to the DCM Non-Aggregatable Reports! You can now choose to include "Site" and "Site ID" when creating a new connection.
If you missed our previous DCM update which explained which dimensions and metrics are included in the Non-Aggregatable Report, you can check it out here.
We hope you find these additional fields and reports useful. If you have any questions, please contact email@example.com and we'll be happy to help.
