Adding more Move Classification options in game analysis

I recently found out that by pressing Shift-D in your game analysis you can see hotkeys to add move classifications and other helpful things to your post game analysis.

I really appreciate this, but am wondering why it doesn't include "good", "great" and "book" moves. I would like to be able to add these tags as well when I am reviewing my own games.

I'm on Windows

This what I see when I press Shift+D

The Game Review feature adds the labels Best, Excellent and Good but these aren't standard terms for annotation. Meaning that if you download the PGN (game file) only the official symbols are included.

They are also interchangeable, they all mean best or almost as good as best. PGNs become much harder to read when you add symbols for every move. Instead you only add a symbol like ?? (blunder) or (!) Great when a move is special. it's meaningless to say good or excellent.

Regarding Book moves,, instead of marking all book moves as such, I find it easier to only comment something like 'out of book' or 'last book move' after the last book move.
