Mine seams to do it, but there is a problem.
I pulled the IC to the top and connected a resistor, then I pressed the button - red bar on bottom - to bottom layer and added another IC and resistor and connected them. In the export it shows the different connections.
The problem is that the IC on the bottom doesn’t have the pins flipped, so pin 1 is in the wrong place.
I’m not even sure FZ has the double load feature but I suppose you could fudge it.
