How do you add keywords from the Normalizer to Master Keyword List (MKL)?

Currently, it is not possible to add keywords from the Normalizer to the Master Keyword List (MKL). The function of the Normalizer is to remove plural keywords prior to adding them to the PPC Keywords tab. In order to add normalized keywords to the PPC Keywords tab, follow the instructions below: 

• Step 1: Manually add keywords and their corresponding search volumes into the Normalizer tab. You can also bulk-add by pasting the keywords with their corresponding search volumes. 

• Step 2: Copy the keywords and their corresponding search volume from the normalized keywords column and paste them into the bottom of the PPC Keywords tab.
