One of the customers is seeking to incorporate custom or saved columns into the current SA 360 connector to enhance their ability to leverage this data at the destination. They have engaged in discussions with Google representatives, who recommended accessing these data via the CustomColumnService endpoint, utilizing the customer ID to Sub-Manager ID approach, and later facilitating the mapping of these columns into their queries. Integrating these custom columns will significantly augment the utility and effectiveness of the data to the customers so kindly consider this request.
