Add 'Crop Playlist' Option for Multiple Screen Layouts

Currently there is no way to display stills on a multiple monitor layout, or video wall (2x2 for example). As a workaround I have to render a video containing the graphic, upload the video, duplicate it four times, and crop each video respectively. If instead, I could crop four playlists, I could change out the content (stills, video, both, etc.) as needed. Not sure how feasible this is from a technical perspective but it would be super helpful for me.
