I am finalizing work on a 300 page book in MS Word 2016 and have created a lengthy index for it. I am facing the following problems in formatting the appearance of the index:



1) In the text of the book I have opted for page numbers of the style "- 1 -". When I give the order to construct the index, the index tool provides the page numbers together with the hyphen before and after each number. I do not want the hyphens; I just want the page numbers.

2) Following each reference word there is a comma, and then the page number. I just want a space after the reference word; commas should appear only between page numbers e.g. where there is more than one listed occurrence of the reference word.

3) All words listed in the index currently start with a small first letter. Each word listed in the index should start with a capital first letter.

4) Most of the words I have added into the index were used in the text of the book in italics. But only a few of the words have been brought into the index in italics, and the rest in standard Roman. It seems arbitrary the way it has happened. Can I set whether I wish the reference words in the Index to appear in Roman or in italics?

Is there a way to systematize corrections for the above four issues, so as to avoid having to fix them by hand?
