Reporting on drobo use year over year?

I’m a photographer and I’m working on year end reports for Fiscal Year '21/'22. My boss is interested to know how many raw elements we added to our physical storage in that period alone. I can easily see how many finished files we uploaded into our online storage since that’s a third party application but I was wondering if there was a way to run reports within the Drobo Dashboard for our 5D and 5D3 machines?
