title: FactoryGirl - create_list increments parameter for each object
body: <p>I'm trying to use RSpec's create_list in a way that, for a specific column, each object receives the value of the previous object + 1.</p>
  
  <p>If Rails accepted ++ notation, it would be something like this:</p>
  
  <pre><code>create_list :entity, 10, priority: priority++
  </code></pre>
  
  <p>I tried using sequence, but the problem is the sequence never resets. I need priority to always start from 1.</p>
  
  <p>How could I achieve that?</p>
  
  <p>Thanks in advance.</p>
