I think you can overwrite some of the constants in Constants\constants.json with a file like this:
[
{
id: "MM_GROUP_NAME",
text: "Company Name"
}
]
That should work in theory. If it doesn't, then that's a bug and I'll fix it. You might also have to restart the game after enabling the mod for it to work, I'm not sure.
I'll check if I can do something about the other stuff, should be easy
