Showcase Pokéstops

I know there is a Showcase currently going on so it makes it easy to find which Pokéstops are showcases. But when there is no showcases active is there any way to see which Pokéstops will have showcases in them? I know Niantic said they would be moving the showcase stops each season (which turned out to be not true). But I'm looking for a way to locate new less crowded showcases without driving all over the state.
