add short copper stubs to pad?

I have an existing flex circuit layout in PADS. The flex fab house suggests adding short copper stub lines from each pad that extend under the coverlay opening, to help anchor the pad physically on the flex cable. For an example of what they want, see the two pads at the center of the image below. Each pad has three short red "stub" copper ears that extend under the green coverlay aperture.

 

The obvious way to do this in PADS is to start a new copper route on the pad, that ends without making a connection, but I don't seem to be able to generate such a route. As soon as I stop without connecting to another pad or net, the entire trace goes away. I could do a separate block copper area or copper pour and assign that to the net, but that seems slow and clumsy. What is the recommended approach?
