Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding General Books and the TEXT inside them

I am trying to create a generic book.. and put some pretty information in it. I can do this by dropping in a Generic Book from the resources and then modding the USE Action tag.

Then add a BOOK action and in the "Bood ID" type the text you want to appear in the book.

In the example of Alexanders Journal, Larian seem to be using a pointer to somewhere that contains the Journal Text ?...

Anyone know where you can link the book ID to some text.
On the USE Actions I can just type a load of text and it will display in the book... but it would be nicer to do it the correct way and enter pointer to the text somewhere... as they do in this example.
