title: Odoo, how to override an action extending it's domain (not overriding)
body: <p>In a module that I do NOT own is the following act_window.</p>
  <pre><code>&lt;record id=&quot;act_465&quot; model=&quot;ir.actions.act_window&quot;&gt;
      &lt;field name=&quot;name&quot;&gt;Act 465&lt;/field&gt;
      &lt;field name=&quot;res_model&quot;&gt;stock.move&lt;/field&gt;
      &lt;field name=&quot;view_type&quot;&gt;form&lt;/field&gt;
      &lt;field name=&quot;view_mode&quot;&gt;tree,form&lt;/field&gt;
      &lt;field name=&quot;domain&quot;&gt;[('available','=',True)]&lt;/field&gt;
  &lt;/record&gt;
  </code></pre>
  <p>I would like to add the following AND criteria to the domain in my separate module:</p>
  <pre><code>('canceled', '!=', True)
  </code></pre>
  <p>I know I could <strong>OVERRIDE</strong> the act_window and the value of domain by <code>[('available','=',True),('canceled', '!=', True)]</code>. However doing so would totally remove what was already in place <code>('available','=',True)</code>. Meaning that if the owner of the base module change it's domain, I'll override his changes anyway.</p>
  <p><strong>Question</strong></p>
  <p>How could I <strong>EXTEND</strong> the domain by saying &quot;I would like to add <code>('available','=',True)</code> to the existing domain&quot; ?</p>
