Please try adding this code snippet to the child theme functions.php file, you don’t have to edit the plugin files:

add_filter(
	'hivepress/v1/templates/listing_view_page',
	function( $template ) {
		return HivePress\Helpers\merge_trees(
			$template,
			[
				'blocks' => [
					'listing_description' => [
						'order' => 35,
					],
				],
			],
			'blocks'
		);
	}
);

I try to keep it simple for now because there would be hundreds of checkboxes for all layout combinations, as soon as Gutenberg editor introduces the templates feature I’ll integrate it with HivePress.
