Using the AD_PERFORMANCE_REPORT I am able to retrieve stats for ads segmented by day. However, for reports such a PLACEMENT_PERFORMANCE_REPORT, and AUDIENCE_PERFORMANCE_REPORT, there is no option to segment these reports by individual ads. I see the option for AdGroupId, but this doesn't provide the granularity of segmenting by ad. Is it even possible to get ad level segmentation via the API in it's current state outside of the AD_PERFORMANCE_REPORT? Thanks in advance.
