I don't want to draw three rectangles to view them separately...can this be done in V5 because I can't figure out how
From the 'Shape' select e.g. the Polygon shape and insert / position as many points as required.
Quick tips: Clicking on an existing line will insert a new point in the line, Opt-Click on a point deletes the point.
You might want to place the shape into its own layer and lock it so it won't interfere with the track layers when editing the layout!
