// Block name prefixes that belong in the category.
$wpide_block_namespaces = array( 'wpide/' );

add_filter( 'block_categories_all', function ( $categories ) {
    array_unshift( $categories, array(
        'slug'  => 'site-blocks',
        'title' => get_bloginfo( 'name' ),
        'icon'  => null,
    ) );
    return $categories;
} );

add_filter( 'register_block_type_args', function ( $args, $name ) use ( $wpide_block_namespaces ) {
    foreach ( $wpide_block_namespaces as $prefix ) {
        if ( 0 === strpos( $name, $prefix ) ) {
            $args['category'] = 'site-blocks';
        }
    }
    return $args;
}, 10, 2 );

## Notes

Set $wpide_block_namespaces to the prefix of your blocks, such as acme/ or wpide/.
