I am using manual attendance and overtime for an employee is calculated. Currently, I need to configure overtime of employee in payslip. I need the overtime include in the payslip as allowence or something like allowence. Because, I want to provide the overtime salary amount to employee. But I cann't configure it. Basically, I tried but it is look like hard to me.

I expect that , when I manually click on one employee's payslip's compute sheet button, then along with all other rules the overtime also added with right calculation to the payslip.
