Propose a 500% increase to the specialized cargoholds for Planetary Industry on epithals. Nothing else about them changes (mass and limited tank remain the same).
This would raise the level 5 capacity for PI only goods from 67,500m3 to 225,000m3.
Alphas capped at level 1 would be able to carry 90,000m3 of goods.
Without getting into changing PI itself, this expands transport feasibility of bulky P0 and P1 goods via wormholes to satisfy adapted build requirements of battleships and capitals.
