[Complete] Why isn't there a Plate 2 x 5 in the parts library?

[wencan]

This is my first time using LeoCAD. I wanted to design a simple 3D model with LeoCAD. 
However, I noticed that LeoCAD doesn't provide a Plate 2 x 5. 
I found Plate 2 x 4 and Plate 2 x 6 in LeoCAD's parts library, but there's no Plate 2 x 5. 
I updated LeoCAD's parts library, but I still couldn't find Plate 2 x 5.

Because LEGO does not produce one (yet) Only real life (LEGO) parts are in the library
