Currently when a user sets up a scheduled report, they can pick the schedule and period included in the report. However, the schedule and period effectively operate independently from each other.

Eg. if I create a "Weekly" report for the "Day" period, I only get the report for the last day in the week and similar for month periods.

It would be quite useful to be able to select a smaller period for the reports with a larger period and include all of the smaller periods in that report.

So for example:
Create a "Weekly" scheduled report that contains all of the "Day" reports from that week
Create a "Monthly" scheduled report that contains each of the "Week" periods in that month
Create a "Yearly" scheduled report that contains each of the "Month" periods in the year
