An example use case of this would be:
"Some of our employees do not take Public Holidays off. Employment Profiles in Appogee Leave always select a Default Public Holiday profile and I have tried assigning a blank one to my Employment Profile but Appogee Leave keeps deleting my blank Public Holiday profiles."
You can use the 'Default' public holiday profile as a blank public holiday profile as it is not deleted by the system. Create other public holiday profiles for the Employment Profiles that do have public holidays.
