Comments on Pages - default setting?

Greetings Tom.
Hope this finds you well.   

I am missing something in my understanding.

On the Custom Comment Form I have post, pages and attachments selected. 

When I create a NEW Post the Add comments is by default checked.

However, when I create a NEW Page - it seams the only why to get comments to display is:

1. Create the Page
2. Return to the Page Dashboard select Quick Edit 
3. then check box " Allow Comments"

Am I missing a setting somewhere that allow for all Pages to have comments. 

I understand also we can have a custom comment go to a specific page or post via added the page/post number to the custom form, but I am thinking I am missing some setting that allows for our custom default form to display on all pages like it does on the posts.

Thank you for your support and your consistency in providing an outstanding product /support package.  You and your team are a breath of fresh air. 

I look forward to hearing from you.
