Transactional Survey Summary - Adding Survey Completed Date

Content

I have trying to add a filter to the Transactional Survey Summary (7002), that will filter these results by the date of "date survey sent" or "date survey completed".

However, I cannot find a field that will work with this report. I have tried Question Responses -> Date Created (question_responses.created), but this seems to be producing incorrect data. 

Is there a different field I should be using? Is there a way to add a filter like this to this report?

Thanks in advance for any assistance!
