 * Hi All,
 * I’m wondering if it’s possible to extend the functionality of a core block via
   a plugin or theme code, without creating a new block.
 * I have a very specific use-case: I want to extend the functionality of the core
   Query Loop block such that if multiple blocks are inserted in a post or page,
   they will never display any post that has already appeared on that same page.
 * Anyone know if this is possible?
 * Ideally, I’d like
 * An old “Classic” theme used on a site I manage had that function on the homepage,
   but it was hard-coded into the homepage PHP, template rather than achieved with
   individual Gutenberg blocks.
 * I realise I’ve bundled two questions together, which isn’t great etiquette I 
   guess. Sorry about that.
 * Alex

 * Yes, there are block hooks for this. See: [https://make.wordpress.org/core/2023/10/15/introducing-block-hooks-for-dynamic-blocks/](https://make.wordpress.org/core/2023/10/15/introducing-block-hooks-for-dynamic-blocks/)
 * I also use them in some of my own plugins to enrich core blocks with additional
   options.
