I started a thread a few weeks ago asking if Favourites could be made to save in the same way as URL Parameters.
That would solve this and other requests, and work across both mobile and web platforms and devices so that everything is synchronized.
Unfortunately it didn't seem to get much traction, nobody from windy even commented.
Anyway, here is the thread: https://community.windy.com/topic/6368/favourites-url-parameters
