Additional default nominal accounts for sales ledger & purchase Ledger.

The ability to have more than one default nominal for sales ledger & purchase ledger. For example on the supplier account there should be an option for the different purchase ledger control nominal accounts which you could select. We need this for intercompany transactions and for this to be separate from the trade payables. At the moment, we would post an invoice which would hit the default purchase ledger control account and then journal this out to another account which we have set up as an intercompany; purchase ledger; nominal.
