Tracks any currency/mark in game. Under custom options add the id for the currency you want to track, and an id for the icon associated with the currency.
You can find a list of currency ids here: https://wowpedia.fandom.com/wiki/CurrencyID
To find an Icon ID go to wowhead, look up the mark/currency you want to track, and click on the icon for it, that should bring up a modal that contains the icon id.
