...much like you can hide labels, hide ooRP systems, etc. with the current setup, one could make a table of data, with the Faction ZoI vs. System.
You could select a ZoI from the interface (both official and generic/indie; for example, Order ID or Order| Primary ID), and it would hide all the systems where ZoI = 0, and show the ones where ZoI = 1.
It would take some time to fill it out, and to keep updated with any ID changes, but it's the simplest bridge I see.
