let's say you want the daily Ad performance stats for an account for January. Currently we (inefficiently) achieve this by making 31 calls (one per day of the month of January) like this:
https://graph.facebook.com/v2.1/act_1376129679271234/stats?access_token=&start_time=1422939600&end_time=1423026000
where start_time and end_time specify a duration of 1 day.
Is there a way where we can achieve this in fewer calls?
Many thanks, Pete
