Is there a way to set the Horizon in the Forecast.Solar

Hi All,

I am trying to configure the Forecast.Solar integration and note that the website API allows a Horizon setting which is essential in my valley situation.
However I cannot find a way to configure this in HA although there has been a note about it in Github (Add horizon to forecast.solar integration #99322).
Is this available or should I try and create a separate integration?

Thanks in advance

I am also looking for this. It would be sufficient if the config would allow to pass custom parameters to the API call. I wonder if this would be possible.
