It looks like someone may have drawn the MKRZero Fz part but I couldn't find the .fzpz. The form factor and pinout is the same... I would need to add the I2C port to the schematic and modify the breadboard view.
I had thought about taking some time to add some of the later more popular boards to Fz, just haven't got around to it yet. These boards are like mushrooms, they seem to just popup all over the place. Everyone is in the Arduino and RPi board business now.
It looks like an interesting little board, it doesn't seem to have quite caught on to the community yet. Maybe because it is still new or too much compensation. I will see what I can do in the next few days to start drawing up Fz parts again.
