No composite reference image option to add to a cover of a book. PS (Beta 27.8)

Hi, I have a Creative Suite. Adobe Photoshop (Beta test).

I’d like to select an area of a book which sits on a coffee table and use my reference image in Firefly as a composite reference rather than a style reference (When I use the style ref, it gets confused and messes up the text and image from the book design). Basically I want the flat graphic (ref) to create a book on the table (I cant add any Prompts in the message window by the way, I guess this is normal). 

Is Adobe Photoshop able to do this?
