Possibility to turn off book collection button from displaying

I have a Picture Story Book app with a Bible built into it. I don’t want to include the Picture Story Book into the Bible collection but rather have it in its own separate collection. But doing this means that in the app, the book collection name is displayed in the upper right corner of the book, which is not ideal for picture books (it displays over the picture). It would be nice if there was a way to turn this off. I don’t need to use this button to navigate to the Bible, but would prefer to get there via the contents menu.
