Hi Mac, Our strictest local inspector allows us to do just what you are describing, per NEC 312.8. For the label described in 312.8(3), we make a custom label that reads:
"Warning: This panel contains feed-through conductors. OCPD for these feed-through conductors are located ..." and then indicate physical location of new subpanel (e.g. directly below this panel, etc.). I hope that helps.
