Binder document mouse hover label - how can I see number of words?

I could not find if this question/suggestion has been asked before.

Can the mouse hover label/tag be programmed by the user to show only desired information about a binder document, instead of the document title and a few first words from the the document text?

For example, I need to see the number of words in a binder document without having to click (and open) the document.
That is, I would like to know the number of words in the document appearing in the mouse hover info. This will be a great help in roughly equalizing the number of words in each chapter (if the chapter was a single document).

Thank you
