While reviewing my own indexing I discovered I missed a few entries. What to do?
While reviewing my indexing I discovered that I missed a few early entries (multiple names, same line). I read a few other responses and didn't find the answer I was looking for as far as how to insert or annotate the missing entries. After submitting this question I went back and discovered that "Add Entries" allows you to choose where to add the entries.
This answers my question and solves my issue. (I didn't see a way to delete the discussion post so edited with the answer)
