Granular Call Reports

One member of staff at our site has requested specific information for a time period of about 4 months. When using the daily filter on the Queue Summary report there is an option for quarter hour reports but when the time period is expanded to months/weeks you can only get the information by hour. Is it possible to get the same quarter hourly report for a longer period of time.

Failing that, is it possible to get very similar information manually from the administration portal?
