Request to change the VAT transactions report to show more details for Cashbook postings

The VAT Transactions report currently looks to SYSTaxTrans.AccountNumber for the Account column. When transactions are posted via the Cashbook such as Nominal Vatable Receipts or Nominal Vatable Payments then the transaction appears with an Account name of CASH. Accountants, Auditors and even HMRC may very well question these 'CASH' entries. My initial thoughts are to have CASH renamed to Cashbook to be more representative of where it originated from. I'd be happy to hear from others for suggested naming conventions.
