Yes, you can label each master page to make it easier to identify different versions for various platforms and formats. Here's how you can do it:
Create a new book and name it something like "Master Pages" or any other name that works for you.
Add all of your Master Pages to this book for quick and easy access.
Once added, select each Master Page from the Left Navigation Pane and update the Chapter Title field with a descriptive name (e.g., "Also By - Kindle" or "Also By - Print").
After making the updates, click the blue Apply Changes button in the bottom right corner. When the verification window appears, select Apply only to this book. This will rename the Master Page in your Master Page options, so you'll see the new title when adding it to future books. However, this change will not affect the title of the Master Page in any current books where it has already been used.
Once you add the Master Page to another book, you'll just need to update the title to fit that book. No need to click "Apply Changes" here—the title change will automatically save.
This method will help you label and manage your master pages more easily. For more details on setting up and using Master Pages, you can refer to this tutorial: https://www.atticus.io/how-to-create-a-template/.
