Removing unit ownership without using a vanilla table

[Ahiga]

As part of my Carthaginian overhaul I was hoping to reform where units fell on the building recruitment tree. Problem is when I tried the old system, using units_to_exclusive_faction_permissions, it didn't work out for me. I was hoping to avoid having to mess with the units_to_groupings_military_permissions table, because it'll make compatability with other mods easier. Likewise, if I use building_units_allowed then it means I have to use the full version rather.

Simply put, does anyone know how to remove ownership of a unit to a faction without using the full body of units_to_groupings_military_permission?

Found a good stop gap solution, just assigning the vanilla troops I want to replace to the civil war faction
