The difficulty with the above is that it is only one of the svgs and likely without the necessary pins. I have around a dozen different sizes of these boards (and that is by no means all that are available). Taking a common (small!) size 10*24 pad version that is 240 connectors on top of the 240 pads needed in both breadboard and PCB (it doesn't need schematic) and then the 480 connections for both those views in the fzp file. Now we need to add on the 8 pads on either end and the 4 mounting holes and ideally the lettering of the rows and commons. Now multiply this by a dozen or more. The only practical answer is either a code change (which I'm not capable of and I doubt is a high developer priority given some of the bugs and finishing part editor) with an unknown release schedule or an external script (which is the more likely if not much less work solution) that creates the fpz and two svg files needed for the board from an input specification (likely the x/y coords of the mounting holes, the number of rows and columns of pads and the number of the edge pads) which generates a different new fritzing part for each board (which is potentially a fair number of parts). I for one don't see the demand for that much work, the current method does %90 of what that solution does and is available today with no work required.
