Profit & Loss Budget Analysis report - Difference columns

Hi,

The report shows a positive variance when the actuals are over the  budget and a negative variance when the actuals are under budget.  This is fine for revenue.  However, when the cost is under budget and shows a negative variance, it can be very confusing especially to someone who is not familiar with accounting.   Is it possible to change that, to display a positive variance when cost is under budget and a negative variance when it is over budget?  Thank you.
