On the home screen you can select products you want to add settings to.
Just click the 
button to add product options to a product.
The Recently Saved Products section will show all the products you have recently saved.
At the moment recently saved products will not show the duplicated options to products. We are working on upgrading this. You will need to search for the duplicated product by clicking “choose product” to edit the product. Or you can use the duplicate tool again to duplicate the settings.
