Is there a way to convert to the old (unevolved art) as the representation of each knight? Perhaps as a future update is this already a thing?

IF you look up the knight in your collection, and click the image of the knight a few times, it will rotate between evolved and unevolved, which should affect how the girl looks on your main screen. I never really checked whether it affects the image in battle as well though.
