Zoho Books Payments Made Report - Allow for Filtering/Customization on Bills Details

When we run the "Payments Made" report, we can select to have a column that displays the Bill #:


However, when we try to filter the same report based on Bill #, that does not exist. There is a disconnect here. Clearly, Zoho Books is keeping track of Bills that are paid and has the payment record associated with the bill and can in fact display the Bill # in a column when viewing Payment info. Why is there no criteria then to allow us to filter based off of Bill # when viewing the Payments Made report. Please assist.
