Via_ferrata_scale

Hey,

In extra_info there is the trail_difficulty depending on sac_scale tag from osm integrated.
Is it anyhow possible to integrate via_ferrata_scale too?
Maybe by changing a function or app.config?
That would be great!

Example here: Way: ‪Bettelwurf Verbindungssteig C/D (2-)‬ (‪521528217‬) | OpenStreetMap
