I have written a three hundred page book in MS Word 2016, and used another software (TextSTAT-2) to analyze the file and create an alphabetical unique word list of 5000 words. I've gone through that word list of 5000 unique words and selected 400 words that I want in the index. So now I have a list of 400 words. Is there a way to add them into the index as a batch, rather than using the MS Word index GUI screen that makes you go to the actual page where the word occurs and add it by highlighting and marking it? I would rather opt to have all the words added at once as a batch, which will save a huge amount of time. The words could all be set as "mark all" occurrences, rather than specifying the occurrence on a particular page.
