How to process annual leave taken in payroll - so the leave loading is applied and the hours taken is deducted from the balance available

I have found is I use the annual leave taken category the loading is applied however the hours balance is not reduced. If I use the adjust annual leave method in payroll this only adds the loading to the pay - and then normal hours need to be added to make up the leave pay but this then accrues annual leave on those hours added.
