Subreddit Tabs (trying to add a custom tab or rename a default tab)

r/HighschoolDxD (some NSFW content but not on home page)

quick link to stylesheet

I currently have the Hot, New, Rising, and Top tabs enabled on the subreddit and I was wondering if there is some way to make a custom tab that links to an FAQ page. I guess it could be the 'Wiki' tab but I'd really like it to say "FAQ" on the tab in the same style as they are now. I don't want the tab to be a separate defined image or anything like that. I'd basically like to rename the Wiki tab to "FAQ" if that's possible.

Thanks for the help!
