A shadow catcher setup in RPRv2085 should make the shadow catcher plane disappear and only render the shadows cast onto it so that you could, in theory, add shadows to an existing image.

I haven't quite got the perspective correct for my "road" with this test image but the theory should work.

This is the setup (sample file attached):

That's for the example.  We are redoing the shadow catcher compositing and this can help as a test scene.
