Analytics Report for Books Comments and History

Analytics Report for Books Comments and History

I want to be able to pull a report in analytics that can spit out portions of comments and history in different modules of Zoho Books. 

For example, when estimates, sales orders, or purchase orders are rejected, I would like to be able to pull a list and say "these are all the reasons these items were rejected" (which is currently only noted on the individual transaction/record). 

I briefly explored activity logs, but it only showed if/when it was rejected or approved, but doesn't list the reasoning that the approver used.
