As shown in the screenshot, a folder is automatically created for WatchKit projects that had "Include Complication" checked upon creation. I'd like to now use two-piece images rather than one-piece ones so that the tennis ball's line is white and not transparent, but I'm not sure where the asset for the twoPieceImageForeground would go.

Do I need to create a separate image set? Would the foreground assets also need separate images for 38mm and 42mm screens?
