Macropod, I have the following question (recommendation).
Imagine, we have a doc document from a book where every chapter has its own numbering, starting from 1,2...etc. And all the numbers in the text body are recognized as a superscript number but not as a footnote anchor. And, we have the corresponding number of footnotes, numbered from 1,2,..etc. - for each chapter of the book.
In this case, we will have a separate numbering for each chapter, starting from 1,2,... - as many times as the numbers of the chapters in the scanned book are...

So, we will have your macro, select the footnotes for the first chapter and we can apply it but then the macro will recognize all the corresponding superscript indexes in the document, having the same numbers as the selected footnotes' ones and the document will look as a mess because one selected footnote will be linked to all superscript indexes in the document with the corresponding to the selected footnote number.

My question is: Can you fix your code in such a way that it can be applied to sections in the doc file (and not to the whole file) and then separate numbering and linking the footnotes, starting from 1,2, ...etc. can be applied for every chapter (section) ?
Suppose the user has manually divided his doc file into as many sections as the number of the chapters is.
And then your code fulfills its procedure for each section (chapter) separately ?
