I'm trying to set up zoho people for managing vacations for my company. Can you please let me know if there is a way to add custom leave restrictions to any particular leave type. For eg: If I have "Paid Leave" as the leave type, I need to be able to restrict an employee to apply for the leave if there are other employees in the same department who have applied for leave at the same time. So basically there should not be duplication of leave entries or overlap of leave entries. Can you please let me know if this can be set up using Zoho people? Thank you.
