air quality Warsaw station issue


I've noticed that air quality station set for Warsaw, Poland (Marszałkowska) is not active - it was disabled some time ago and is not even mentioned by Główny Inspektorat Ochrony Środowiska (source) on it's web page. I believe it is the reason for air quality results for Warsaw to be incredibly wrong all the time. Is there a way to change the station on my own? If no, could you please provide such option in the future / change the station to one that actually works?

Thank you,
