Extend Rate multiplier in Pay Items for Payroll to include three decimal points

When working through employee pay rates alongside fairgov.com.au awards it is required that you may have to pay additional on base rate. This may be a decimal point percentage e.g. 12.5%. So the rate multiplier would be 1.125. The current system only allows for two decimal places 0.00. Can you please update so we can sit precisely alongside the awards from farigov.com.au.
