P32 Report to show Liability Due and Liability paid

when we come to generate the P32 Report, it shows the totals for the months where liability has been paid previously as zero and therefore the YTD Liability is incorrect and does not reconcile so clients cannot see the total liability for the YTD or the period we ran in parallel. The total for amount carried over from opening balance shows on the report, however any periods we have ran in parallel, this will show the breakdown but does not show the Total Due for the period. Ideally, we need a new column added to the P32 CSV report so we can see “Total Liability Due” and “Total Paid” for example. The P30 has these similar headings but we cannot use this report as it does not show history
