Add new option to import custom json file

I was wondering if there is a way to add an extra option to import an external JSON theme file and include it in the one-click import process. Something like this:

function ocdi_import_files() {
  return [
    [
      'import_file_name'           => 'Demo Import 1',
      'import_file_url'            => get_stylesheet_directory_uri() . '/demo-data/demo-content.xml',
      'import_widget_file_url'     => get_stylesheet_directory_uri() . '/demo-data/widget-content.wie',
      'import_customizer_file_url' => get_stylesheet_directory_uri() . '/demo-data/customizer-content.dat',
      'import_preview_image_url'   => get_stylesheet_directory_uri() . '/screenshot.png',
      'preview_url'                => 'http://test.test/',
      'import_json'               => array(
				array(
					'file_url'    => trailingslashit( get_stylesheet_directory_uri() ) . '/demo-data/gp-export.json',
					'option_name' => 'GP_option_name',
				),
			),
    ],
  ];
}
add_filter( 'ocdi/import_files', 'ocdi_import_files' );

Would that be possible? Also, would it be possible to add the extra JSON import to the manual demo file import list?
