Currently the only options for the pipeline are to select which days of the week, and once the schedule is set, it aggregates the results so that they accumulate over time. 

There should be better scheduling such as:

• At intervals (such as hourly or even monthly)
• Allow the user to pick how far back they want the reports to collect, such as
  • Since the previous day
  • Since the last report
  • Since the beginning when reporting was turned on
  • etc.
