title: Magmi: Import group price based on customer group
body: <p>I'm trying to import some group prices based on client group.</p>
  
  <p>I have something like this:</p>
  
  <pre><code>Customer Group: Common Clients
  Customer Group: Registered
  </code></pre>
  
  <p>I want to have two different prices based on customer group, I can do it on group prices section on the Magento product admin, but I need to import a batch of products using Magmi, others fields, works great, sku, price, special_price...</p>
  
  <p>I have added to my csv this columns:</p>
  
  <pre><code>group_price:Common Clients, group_price:Registered
  60,43
  </code></pre>
  
  <p>I'm also using Group Item Processor plugin: <a href="https://github.com/tim-bezhashvyly/magmi-grouped-price-plugin" rel="nofollow noreferrer">https://github.com/tim-bezhashvyly/magmi-grouped-price-plugin</a></p>
