Fences change size

I will spend a good amount of time setting up my fences to certain sizes on my main monitor with the icons grouped in each Fence. Occasionally, like when I just updated the Nvidia Video driver, when the monitor resets, the fences all change size and get pushed together.  I then need to manually resize each fence group to the way I want it.

Is there a way of configuring fences, then saving the configuration so when this happens again, I can simply reload the configuration file?
