I'm adding new effect to effects group (let say industry_exp to effect_definitions_industry.x ml). I copied file to mod, and just added another entry and it is working smoothly. BUT! Is there a way to add just entry to effect group without coping whole file (and overriding it)? Something like push to array, not creating whole with new elements. I'm asking it for sake of compatibility with other mods, if they will also modify this file, there will be a problem :C And i don't want to create new, mod specific file (it would display badly on pilot profile).
