How to add custom character modifier?

[Issak]

I'm trying to add custom character modifiers to some of my culture groups, but they won't show up in game. The horse culture, for example, has the "mongol_opinion = 20" under it's character modifiers and that shows up just fine in game, but if I try and add "saka_opinion = 20" it dose not show up. What file do I need to change to get this to show up?

Add it in common\modifier_definitions, and add some localisation.
