I've created a very simple custom rectangle using two lines: one horizontal line to create the bottom of the rectangle, and another line with two midpoints to create the top and sides of the rectangle. I used two lines because I want the top corners to be rounded while the bottom corners remain square. The two lines are connected at their endpoints to create a closed shape (see attached).

I now want to fill the shape with a color, but Omnigraffle doesn't offer me that option because it handles it as two lines instead of an actual closed shape. Grouping the lines into one object still does not allow me to fill the shape. Is there a way to accomplish this? Thanks!
