Currently if you want to look at 5 years of data, you would have to set-up and run the activity report 5 times. Instead of running the report for each time frames, set the date range for the specified time then have the report engine look at the parameter to execute the 5 reports in the time-frame corresponding to each year and label files to indicate time-frames. This way BOX controls resources and the admin would not have to do this a multitude of time to get the report data.
