Require the option to choose whether VAT Code is pulled from PL Account or Stock Item Details for PO Entries

Currently in Sage 200, if you enter a stock line onto a Purchase Order, the VAT Code is pulled from the Stock Item Details. On the Sales side, it is possible to choose whether the default VAT Code against the SL Account is used for Sales Orders & Invoices, rather than the Stock Item Details. On the SL Account Trading tab, there is a tick box for Use VAT code as Invoice and Order default. It would be useful if this option could also be on the PL Accounts.
