Rounding issues on iFinance

Now that VAT is implemented on private schools, some bills have rounding issues that are affecting the total gross invoice amount. There isn't a way around the rounding errors of units and the VAT amounts to ensure the gross amount comes to the correct price. Therefore, could we either have a rounding discrepancy box where this can be reviewed/written off or more decimal places in the unit box but keeping all other boxes at 2 decimal places.
