Set "termination" variables via API

Hey,

I would like to set/ update termination related variables for a Person / their Employment. It seems like they are already included in the API Response of GET https://api.personio.de/v2/persons/:pId/employments.

"termination": {
        "last_working_date": "2026-01-15",
        "reason": "123",
        "terminated_at": null,
        "termination_date": "2026-01-18",
        "type": "QUIT"
}

However I can´t seem to figure out a way to set these kind of values via the employments or persons endpoint directly.

To have this ability would be really neat as otherwise I can´t terminate an employee via the API.

Best regards
