How do we enter TOIL into a timesheet in Reckon Payroll?

We have always manually entered employees hours into Reckon Payroll and for any TOIL worked/accrued we entered with a - to reflect the time taken off of the extra ordinary hours entered. This then adds the TOIL hours to the TOIL leave balance. Then when TOIL taken we used a + amount to reflect the time taken and amended ordinary hours respectively, meaning TOIL leave balance is also amended accordingly.

Is this the correct way to enter it and if so, how do I enter a - figure against TOIL pay item on a timesheet?
