Heya. So I've been working on a mod that adds a new religion and several cultures to the game. I've been editing the histories to make said religion and cultures appear in the appropriate places based on the date, however I've hit a snag when trying to apply my changes to the character history. For example I only want to apply the religion to Irish characters up to 1172. But the only method I can think of to do this is individually find every character that existed before that point and change it from Catholicism....out of a list of a ton of characters. Is there another way I can go about implementing the change?
