There is a three pole double throw toggle available here:
otherwise you (or someone) could swipe the breadboard svg for one of the Taiway toggle switches in core parts (which have a reasonable breadboard representation which is the difficult part) and modify the svgs to be double pole double throw reasonably easily.
(edit:) Mostly we would need the layout of the pins in pcb view (which likely means having the exact model number of the switch you want to use if you care about pcb) so the pin spacing on pcb is correct the rest is fairly simple.
