Multiple Simultaneous Z-Wave Firmware Updates on Hubitat

Did a quick search and surprisingly didn’t find anybody with this question:

Has anybody done a batch / simultaneous firmware of multiple switches via the Hubitat Z-Wave updater?

I have upwards of 30 Red Series dimmers and an older C4 hub in my house and am somewhat terrified of slinging all of that traffic around the mesh. So I have inconsistent FW versions throughout the house because I go one by one on rainy days like today.
