Reuse newsletter sign-up block?

I couldn't find an answer to this by searching, so just wondering if there's a way to reuse a newsletter sign-up block that I've previously created. I want to put one at the end of blog posts, and don't want to have to create it every time. I see that I can name them, but it doesn't appear I can reuse those named one to plug them in with one-click.

You can achieve this but requires a custom plugin

First, install Section Loader Supreme Plugin (affiliate link) or this link (non-affiliate link)

Next, create a page in Not Linked

• Name: Reuse Newsletter
• URL Slug: /reuse-newsletter

Next, edit page and add a Newsletter Block

Final, edit blog post where you want to place Newsletter > Add a Block > Choose Code > Paste this code

<div data-wm-plugin="load" data-target="/reuse-newsletter"></div>

Bonus

In case you want to add a newsletter to all blog posts, above Pagination, you can use this code to Post Blog Item Code Injection

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
  setTimeout( function() {
          $('div.wm-load-container').insertBefore('body[class*="type-blog"].view-item section#itemPagination');
    }, 3000);
});
</script>

Result

Thanks for the link and for the detailed instructions, will give that a go!
