add_filter( 'gravityflowpdf_content', 'sh_pdf_content_modify', 10, 4 );
function sh_pdf_content_modify( $body, $file_path, $entry, $step ) {
    $body = '<h1>Inserting a custom title before template content</h1>' . $body;
    return $body;
}

Prevent the {all_fields} merge tag from shrinking all the text in the table for long tables.
