It's a common misconception that you can connect only one wire to one point. If it's a screw terminal (likely, for 40A) you can easily squeeze a few wires in it.
You can of course use a single wire as power rail, and then basically daisy chain them. Just make sure it's a wire that has no problem carrying the full 32A you need - that'd be a 2.5 mm2 for wires in air, or 4 mm2 for wires that are on the surface or otherwise don't have easy heat dissipation.
