Spell Perfection (Fireball) for Theologian Cleric

[gautrau]

Is there a way to get the Spell Perfection feat to recognize Fireball as a valid choice for a Theologian Cleric with the Ash or Fire domain? It's a standard for a blaster cleric build, but HL doesn't give the ability to select it. I've even tried to add Fireball to the cleric spell list using the permanent adjustments. Am I missing something?
