Holidays Configuration

In Organization Settings, you can create a list of holidays. These are not counted as workdays from workflows.

Is there any way to import these holidays or edit these entries directly? As far as I know, there is no such feature documented.
Maybe someone here knows of a possibility I don't know about?

Any way would work for me: txt file import, API call, database manipulation etc.

EDIT: Found it in the database. Any other way would still be appreciated.
Settings is an XML column.

SELECT settings FROM [dwsystem].[dbo].[DWOrganization];
Organization -> General -> Calendar -> Holidays

      <Holidays>
        <Holiday name="Holiday 1" date="2022-11-21" />
        <Holiday name="Holiday 2" date="2002-11-21" />
      </Holidays>

PS @DocuWare why is formatting so broken? 

Hi Simon H. Hellmann,

there is currently no way to import a file with a list of holidays into the configuration. 

The formatting is sometimes broken. The service provider already fixed something which helped in most cases, but sometimes it is broken even after the fix.
