Summoning Limit

Hi guys i picked up BGEE in the steam sale and was playing a cleric mage because i wanted to be able to summon an army only to find out i can only summon 5 creatures across the entire party, and since i have a necromancer, cleric, druid and myself as a mage cleric this limit was very disappointing, is there any way someone can mod it out of the game so i can have my army please
