report.GetTable USER_ENGAGEMENT date field?



I’m trying to get user engagement data by date, what’s the best way to go about this? Currently I am calling the USER_ENGAGEMENT report (id = 11) using getTable service in the API…but maybe this isn’t the right one for what I am after since the data could be summarized if you choose more than a single day range. I’m pulling down several columns of information, but date doesn’t seem to be one of them. How do I add this to my query or what other call should I be making?
