I grabbed the svgs and fpz from the core parts directory breadboard2 and then the associated svgs from the svg directories and built a new part from them 
Fritzing appears happy with it even though it isnât blessed by parts editor.
Here is a copy to save you the trouble:

Thanks @vannep. Bypassing tye parts editor? You rebel you!
I am making a part shortly that needs to be positionable below any breadboard or stripboard. Any ideas what edits I need to make to the fpz to make that happen? Thanks.
Iâm not sure you can, one of the features of the breadboard family (Iâm told by @steelgoose who is the source of most of my good information 
) is that they are always on the bottom. Steve may know of a way though.

I only really need it behave like a breadboard and respond to send to back, thatâs good enough.
@sgparry0407 I donât think it is possible⌠You would probably need to make it as a breadboard part moduleId="???_BreadboardModuleID" then I suppose you could slide one breadboard part under the other breadboard. But you would loose some functionality⌠like no schematic or pcb. Another option would be is to make the breadboard as a part and not a breadboard. Take the âBreadboardModuleIDâ out and rename it. Then you could move it to any layer (above or below). I helped someone with a part a long, long time ago with the breadboard part that had no pcb/schematic and part of it with pcb/schematic. As I recall, we had to the the hybrid for the breadboard pinsâŚ
This could be even uglier, as the part on top I am using is stripboard. Once I have the basic âlowerâ part, Iâll try a few permutations and get back to you.
You may be able to make a new strip board part (probably the same way I did breadboard) and change its family name to something other than breadboard. I think it is the family name that trips the âalways on the bottomâ code.

The strip boards have a functionality where you can connect the holes together⌠If you take the function out of it and make it a part, I doubt if any of that will work. You may be able to save the strip board as a part (a board with a bunch of holes) but the likes to connect the holes probably wonât work.
The strip board is a funny animal, you can size it and link the holes, it is probable generated on the fly with some kind of Python script or something.
