Providing link to the wiki is very useful! If your wiki is on UCP, then creating new achievement tracks isn't possible - at least not so far; I don't know if it'd be possible in future. You can to inquire if they're willing to explain any estimated plans about the tracks feature.

Also, the Discussions are a better suited place to seek wiki-related help!
