Hi @raphaelfx,
Thanks for your answer. That’s very interesting. As it stands, I don’t think that OJS would report based on this information in a report. I believe that there is some work going towards this, as specified here: Add custom review forms to reviews report · Issue #2051 · pkp/pkp-lib · GitHub (for 3.4 - although it is not clear to me if this work would match what you have in mind).
I have flagged this as a feature request, however, for our team to review, could I ask that you reformat/rephrase your request though? Such as in the example here (using the bolding headings there): Improvement of PKP's OJS installation statistics site (https://pkp.sfu.ca/ojs/stats/)
