That isn't possible on UCP. At least, not yet. Right now, Achievements on UCP does not allow custom edit tracks; which is what you are referring to. Wikis that have custom edit tracks had it carried over from the older platform which did allow them.
Yeah, Achievements on UCP has limited functionality for the time being. However, this might get fixed with the upcoming "bug squishing" sprint Fandom is doing. We'll have to wait and see.
