Detailed monthly report on PBIKs

We payroll cars and medical insurance and need to accrue the cost of class 1a NICs due on these each month in out accounts. We want to allocate the NIC on cars to one nominal ledger code and the NIC owed on medical insurance to another code. But there is no monthly report which splits the PBIK figure out between type. In Apr26 everyone will be payrolling benefits so this will become critical for every employer.
