You cannot add new morphs to an already saved Genesis 2 in Poser. You will need to re-import the figure through DSON for those morph dials to appear. The only solution to your issue, load the Poser saved character into your scene, import a new Genesis 2, select the Poser figure, Edit>Copy, then select the imported figure, Edit>paste. The new morph dial settings will appear in the new figure. Dial in your new morphs.
