title: Show total sales in the product title everywhere in Woocommerce
body: <p>I'm building an art gallery with woocommerce.
  each product has a limited number of prints (for example: 100).
  I'm looking for a way of showing in the product title, the number of the current print based of the number of prints already sold, so for example if 20 prints where sold, the product name would be "NAME OF PRINT - PRINT NUMBER 21"</p>
  
  <p>So far I have been searching the web for a solution, but could not find the right way.</p>
  
  <p>Any help is appreciated.</p>
