Can I set different leave allowances for each employee?

How to Set Employee Leave Allowances in TimeOff
In TimeOff, there are two ways to set up leave allowances:

Department Allowance
You can assign an allowance to a department. All employees in that department will automatically inherit this allowance.

Individual Allowance
If you need to set a different allowance for a specific employee, go to:
Employee Details → Allowance Tab → Nominal Allowance Section

Here, you can override the department allowance and enter a custom value for that employee.
Add new employee button on Employee screen
