What is the improvement or update to the Wiki you wish to see?

Under https://metamanager.wiki/en/latest/files/builders/plex/#number-attributes, note 1 states: "1 You can use current_year to have PMM use the current years value. This can be combined with a -# at the end to subtract that number of years. i.e. current-2" At the end, this example should be "current_year-2"
