title: Woocommerce Admin Orders hook to limit number or total orders displayed
body: <p>I am looking for an add_filter or add_action that I could put in functions.php to limit the amount of queried or cached results in the orders admin edit page (shop_order).</p>
  
  <p>We currently have about 15,000 orders and the queries are taking 20 seconds or more to load. Limiting the results to last 1000 or 2000 would suffice. </p>
  
  <p>Transients have been deleted, database optimized. usual culprits identified. But I am not arrogant enough to know all so any suggestions are welcome including modifying the query.</p>
