Recurring Transactions: Set up transactions for loan repayments with monthly interest components

It would be great if MYOB had the ability to have HP or loan repayment schedules entered so that payments can be automatically allocated for each payment period according to the loan documentation. This would be so handy rather than having to work out the principal and interest amounts manually for each payment, preparing a schedule in another form of software such as excel or doing a recurring entry for each period.
