The pad does not have a schematic .svg, so there is no way to make it appear in the schematic view. One why is to overlay the pad on a single pad connector and have one pin in the schematic view. Although that is kind of counter productive and you probable have already tried that... The only other way I can think of is to create a one pad part... each pad would have one schematic pin... the breadboard view could be left out if you want. The problem is that the pad is not adjustable, therefor you would need to make a bunch of them with different size pads... once you had all the different size pads made up it would not be to difficult to drag on to the board to make a footprint...
If it were me, I would setup a parts factory on a graphics editor. It would be difficult to do in Inkscape, but AI or CorelDraw it would not be that difficult. Just make a series of pre-made pads and pins and save them on a page then drag them on the a parts page and create an instant part without using FZ parts editior. The problem is that it takes a little bit of a learning curve to get to that point where you can make parts ready to go efficiently.
