@cayenne -- not sure if this answers your question, but -- go to the adjustments pane. by default it only shows certain possible adjustments. look for the drop down menu on the adjustments pane that says "add adjustments," it's to the left, not too far below the top of the pane. click on it. it will display all available adjustments, including noise reduction. if you click on any of them, they will then be added as default adjustments that appear will whenever you open the adjustments pane.
