title: Woocommerce - how to add big amount of variations?
body: <p>I create an e-shop in Woocommerce and I have a problem with inserting variations. I have 20 colors (1-20) and 4 sizes (A-D), so total of 80 variations.</p>
  
  <p>But my colors are in 3 different price groups (e. g. 1-7, 8-15 and 16-20) - so I need to set prices for every group and every size, e. g. like this:</p>
  
  <pre><code>  | 1-7 | 8-15 | 16-20 |
    ----------------------
  A | $20 | $25  | $30   |
  B | $30 | $35  | $40   |
  C | $40 | $45  | $50   |
  D | $50 | $55  | $60   |
  </code></pre>
  
  <p>I could create all combinations of these two factors, but that would be really difficult because there are 80 combinations in total.</p>
  
  <p>So I would like to be able to select multiple colors for one variation (kind of <em>or</em> oparator), but it doesn't seem to be possible in pure Woocommerce.</p>
  
  <p>How can I achieve inserting multiple colors as one variation without having to create a new variation for each color? Is there a plugin for this?</p>
