Okay. This is the first time I've done this, so it helps that you mentioned to dig for "CODE" in the MTC buttons -You have to put it in code tags or it doesnt work
Code:
// ==UserScript==
// @name SEQUIN
// @namespace http://tampermonkey.net/
// @version 1
// @description
// @author Concise
// @match https://s3.amazonaws.com/mturk_bulk/hits/*
// @grant GM_log
// @require http://code.jquery.com/jquery-3.1.1.min.js
// ==/UserScript==
$('input[value="NoPearl"]').click();
$('input[value="NoSequin"]').click();
$('input[value="NoStud"]').click();
