You can contact DxO with a request to add a specific lens (or lenses). If they receieve enough requests, they might add it.
If nobody requests anything, nothing will be added. They have limited resources an try to accomodate for the most 'popular" lenses. Just have a look at what is available for the more 'common' brands
