Default "Preferred Art" behavior

I've noticed that the preferred art - at least on mobile - seems to default to the newest set with available art. I'm the kind of player who loves to see the first printing of cards, and got many cards to display the earliest version by default by simply not downloading card art for reprint sets - but any card that's been reprinted in a set with unique cards defaults to the new printing. Is there any way to change that default behavior? Going through thousands of cards and individually setting the preferred art is too tedious for me (and would likely give me carpal tunnel), I'm afraid.
