title: Woocommerce price on attribute
body: <p>I have problem with WooCommerce. I have two attributes - 5 sizes and 10 colors (total 500 product variations). Price is based only on sizes (for colors it does not matter). </p>
  
  <p>How can I config product variations prices of a variable product without editing 500 on them? </p>
  
  <p>For example:</p>
  
  <p><code>RED S = 10$
  RED XL = 15$
  GREEN S = 10$
  GREEN XL = 15$</code></p>
