Leave applications for employees with specific work days

Hi, we’ve started using ERPnext and want to handle leave applications with it (not the full payroll process.

I have a question about when employees only work on fixed days a week e.g. let’s say Monday, Wednesday and Friday.

Would I create separate holiday lists for employees with different work days and define those days as weekly days off? Is there any other way to define the actual working days per employee?

What is the intended way to solve this? I didn’t find a solution for V13 on here or in the documentation. Using holiday lists seems a bit clunky, as I still need to add the actual holidays and can apparently only select 1 holiday list per employee.

Thank you for any help
