One way is to use multiple configurations where the fields are changing in each configuration, then turn on all configurations in your 3D layout. I have done this for a system with 9 fields per configuration and 6 configurations, so I am seeing all 54 fields on the layout plot. 

Thanks Sean, that is a helpful trick.  It seems to me that 12 is an arbitrary (small) number and there should be a way to pick your own limit, within reason.  I wanted to make a grid of 4x4 or 5x5 field points for some PowerPoint slides & didn’t want to leave the FoV partially empty.  It just looks like an error on the slides; takes time to explain.
