Can I Add or Remove Fields From a Facebook Ads Prebuilt Report?

No. It's not possible to modify existing prebuilt reports. To fetch specific fields or reports, you must create a custom report and specify the required fields.

You can create custom reports while setting up a new connection. For existing connections, go to the Setup tab and click Edit connection details. Then, follow step 4 of our Facebook Ads setup guide.

For examples of the types of custom reports you can create, see our Facebook Ads custom reports documentation.
