Hi Tina,

Luke from the Product team here. Thanks for submitting this feature request.

Our connector fetches a list of available fields from the Google Ads API when loading our custom report feature. So when a field becomes available for the API versions we're using, it becomes available in our custom report feature. We're currently using v20, so we support platform_comparable_conversions fields.

However, Google only made this field available on the campaign resource: https://developers.google.com/google-ads/api/fields/v20/campaign. Search on that page and you'll find mentions of platform_comparable_conversions* fields. Google did not make it available on ad_group nor ad_group_ad, so there is no way to report on this metric at those levels.

Unfortunately, we're unable to support your request unless Google adds these metrics to those resources. If they do, we'll support them right away because we always fetch the list of available fields.

Let me know if you have any questions.

Cheers,
Luke
