I like the idea that I can schedule a report using the Improved Reporting engine and can set date ranges and schedule the frequency for getting a report. However, there is no way to set up the report to automatically update/change the dates and date ranges for the successive reports. The improved reporting engine is incomplete without this functionality.

For example, in the image below I have set up a one-week date range for an assessment for a course. The instructor wants a report emailed to her each week that lists the students who have completed her courses during that week range and their scores on the final exams. She wants an updated report each week. I would love to do that for her, but I can't.
