Adding multiple pages with custom print template?

[arrghh]

I have created and saved a custom print template that has five 5x7 fields arranged on a 13x19 sheet of paper. I can add images to these fields and print the page, no problem. But I would like to set up multiple pages with this template and then lay out all my images before printing. When I try to ADD another page, and apply the same custom template to it, the first page disappears along with all the photos I had placed, and a new page with my template replaces it. I dont understand the point of the "Add Page" button if it merely wipes out my page 1 and replaces it with a blank page. Does the "add page" button only work for the canned/pre-set templates and contact sheets?

Is there a way to keep adding new pages with my custom template, so that I can keep placing photos and end up with multiple pages of images, and then save that set of prints as a project/print job in LR -- or at least as a multi-page PDF? I am not trying to make a Blurb Book, I am trying to print and bind my own book with about 50 5x7 images, and I want to print them five to a sheet, and save this layout so I can reprint it later or edit it if I decide to make changes.

Make sure you select the right 'package': https://helpx.adobe.com/lightroom-classic/help/print-module-layouts-templates.html

@arrghh  You would be better to actually design a Custom Page in the BOOK Module to then create JPGs or a PDF.

The one limitation is that you are limited to the provided default Page SIZES as given in the Book Settings panel.*

a) Design a Custom Page Template (in the book module). Adding cells, re-arranging, re-sizing, etc, on the page.

b) Save as a Custom Page Template. (EDIT: Note- Custom Page templates are specific to the Page Size selected! )

c) Create (Edit) an Auto-Layout Preset- using your Custom Template

Now to create the JPGs or a PDF

1) Set the Book Settings > Book  to [JPG] or [PDF]

2) Select a Size, eg. Standard Portrait  

3) Set JPG or PDF attributes- Quality, Profile sRGB, Resolution PPI, Sharpening, Media.

4) Choose your saved Auto-Layout Preset in the Auto Layout panel.

5) Click the [Auto Layout] button.

Your book will auto fill with all the images on the filmstrip creating as many pages (all with the Custom Page) as required.

Hint: Have images pre-sorted (in a Collection) as you want them on the book pages (it lessens later re-arranging)

6)  Click on the button [Export Book to JPG]  or the [Export Book to PDF]  

*If you [Export to JPG] you do have the ability to use Photoshop to crop the JPGs to an exact ratio if the default Page size templates are not exactly what you want.
