I kind of keep a running "journal" on occasion. The best thing I have found at this time that works is keeping it on a word document, copy & paste into a new book then seal and lock it down. Yeah it's a little bit of a pain but it allows me to keep everything I have put in the book prior and also update it when needed and saves buttholes from putting all kinds of junk in it.
Your idea is a decent one but can not imagine how they would go about doing it. Also, probably not too much call from the players on such an idea outside of maybe me and you lol
