Help syncing notes to words

[r3n]

Hello!

I'm wondering if there's a way for me to add a note to a particular word and then have that note show up for each mention of the word in the book. I'm reading War and Peace and having trouble keeping track of all the characters, so it would be great if I could write up a brief description of each of them and then attach that description as a note to each mention of their name in the text. Is this possible?
