spawning character into existing army

is it possible to spawn a named character in to an existing army on event?
lets say my army led by a captain is victorious, i would like that army to get a general. preferably with the same name as the captain, but that is not to important. i do not want that general to appear in the family tree, so i rather have it happen by a spawn_army entry in campaign_script than by "the man of the hour".
this is my campaign_script so far. how do i alter this to spawn the character in to the on fore said event? or is it at all possible?

script
