How to annotate games in a pgn file with "{last book move}"

[Jonathan003]

I have a pgn database of about 80.000 games.
The games don't have any annotations.
I want to annotate the games, so there is an annotation "{last book move}", in the games.
I want to annotate the games with a CTG book or bin or abk book loaded.

Afterwards I want to search for games with this "{last book move}" annotation, truncate the moves after this annotation and remove duplicates (also games included in other games).

I can do it with Fritz from Chessbase by selecting al the games, and doing a blundercheck with the option depth = 0
But it is very slow. It will take more than 24 hours on my pc to complete the task.
I want it to be fast and I'm only interested to have this "{last book move}" annotation in the games.
Does anyone know of a better and faster approach?
Maybe with Scid or Arena or Banksia?
Or maybe with some simple Python script?

Here is a sample how I want the annotated games to look:
