Is it possible to have different wallpaper slideshows on different monitors?

I currently have two monitors in the landscape position that have a single slideshow that cycles every 30 minutes so the left and right monitor show different pictures from an album. However I soon will be changing out one of the monitors and putting my secondary monitor in a portrait position. Is is possible to have, for example, one wallpaper slideshow cycling through landscape wallpapers on the left screen and a different wallpaper slideshow cycling through portrait wallpapers on the right screen? It seems to me like you can only select one folder for the slideshow to grab wallpapers from for both screens instead of individually assigning them but maybe I am missing something. If Windows can't natively do this is there some sort of free or paid software capable of this?
