Export flight path as KML

Is it possible to add a feature to export the KML of a flight plan rather than just giving the option of exporting it as waypoints?

There's a button 'View KML' on the right which downloads a file network.kml, which then contains a reference to http://127.0.0.1:56781/wps.kml which contains the information I would like to download.

Is is possible to allow a direct download of wps.kml using a button here?

Start by finding the handler for the existing “View KML” button and tracing how it downloads network.kml and references wps.kml. Confirm where the flight-plan data is assembled and how the UI exposes downloads. Done means a button or equivalent action directly downloads wps.kml with the requested flight path.
