So for my mod, what I'm trying to do is make it so that people with a specific inheritable trait has bonus acceptance modifier to marriage proposals with other people with that trait, and negative modifier if they don't. Just in generally making it that they tend to marry and breed together and not with non trait bearers. Is that hardcoded in the Marriage decision or is there any way to make it easily standalone? I don't want to have to overwrite vanilla files and cause conflicts seeing as I run HIP. Couldn't find anything on google so any help would be appreciated.
