Product team is planning for a new feature called "Drill-through" / "Linked Report" (Terminology might change). It does allow you to link two distinct reports. In other words , It allows you to click on a cell value of the main report and that would open the linked report. Since these two are Independent reports, you will have flexibility to setup the report the way you want.



This functionality exists today in a specific area (Usage section in CS 360) of the product and not as a generic solution.



Navigate to CS 360 sections setup (Layouts), You would notice that "Report" option against "Usage". Click on it and setup the linked report / Drill-through report. 



Once the setup is completed, then navigate to CS 360,  click on a value on "Usage" Trend report, it would open up linked report at the bottom section of the  Usage chart.

This feature is already there. When you build your report click in the drill in, grab the column header, and drag it into the position you want it. This works for both C360 and dashboards.

I tried saving the new arrangement of my fields in the drill down report but they won't save, they keep reverting back to the default setting.  First I save it in this order:

Then I check it again and it's reverted back to this order:
