To clarify: The survey questions have been translated and added as a translation. The messages (back, save, etc) are still in English. Can I import in such a way that it will leave the translated questions in place and copies the translated messages?
I could imagine uploading an Excel with the already translated questions as blank fields, but am not sure.
I’ve actually answered the question myself by testing. FYI, the answer is yes, you can upload an Excel with the already translated questions as blank fields. The blank fields will be left alone.
