Produce - Select layout (InDesign import)

If your design file consists of multiple layouts it is possible for the content creator to select which layout to use when creating a new document. A dialog is shown as below, with all the different layout options and how many pages they include with the option to click through the pages if there are multiple (a preview is shown in the area marked below): 

After selection the editor is opened with the document layout. It is not possible to change layout afterwards but a new document must be created if so.
