This is fantastic -- IF I have to write a work around.

I wouldn't have been even closely where to begin searching the archives. Much
thanks.

What I am up to is modeling the ARP 2500 modular synthesizer.

https://encyclotronic.com/synthesizers/arp/2500-r167/

Instead of planting arbitrary knob positions and the matrix switch panels for
every instance of module, I used some data abstraction. An entire System is a
dictionary, divided into one or more cabinets filled with info on the modules'
state. For now the data structure is:

//=============Code==========

#declare System = dictionary {
  .ACabinet: array <mixed> [ slotsInCabinet ][ controlValues ] {
    // First slot
    { moduleID.float, panelSize.float, topJackPosition[20].{locVect, rotVect},
bottomJackPositions[20].{locVect, rotVect} }
    //  Middle slots
    { moduleID.float, panelSize.float, topSliderPositions[],
bottomSliderPositions[] }
   // Last slot, same as the first
  } // end of .ACabinet
.... more cabinets and components
} // end of System
