Analytics Usage report for "Reports" - Differentiate "Shared Custom Report" from "Shared Report"

Hello-

I creating a analytics usage report to see the number of requests on all the reports in the system so we can do a clean up and delete reports nobody uses. I was able to get most of the data but when I report out the "content type" field it only says "Shared Report".... as you can imagine there are tons of pre-defined reports that the system already has and the another ton that are actually custom shared reports that we have created over the years so when we are trying to review the reports is hard to find them.
