MYOB Business Payroll Payrun Decimal places

When doing payruns in MYOB Essential for salary staff, when they had a leave type taken you had to change the base salary quantity to get back to the gross monthly amount they should get paid each month.  In the new upgraded version it only lets you add the quantity to two decimal places.  This now means that your are either over or under paying each employee each month as you can't change it to get it to the exact monthly amount they should get paid.  If a company had a lot of employees this "rounding" error could be quite a large amount overall.  The total box is unable to be edited either so you can't directly amend that either.

Is it possible to increase the number of decimal places in the quantity fields?

Thanks
