Opening estimated leave accrued since anniversary

Hi, I've recently started using Essential Payroll. My employee is a permanent part-time employee who works three days a week for six hours a day. He is entitled to 72 hours of annual leave per year, which equates to 6 hours per month. The anniversary date is January 1st. In my previous system, he has 156 hours of annual leave as of August 1, 2022.

How does the rolled-over leave work in this Essential Payroll? Assume he does not take any hours of leave this month; is the 6 hours of leave for the month automatically added, and the balance on 1 September will be 162 hours?

Do I need to fill out the Opening estimated leave accrued since anniversary?
