title: how to make sure that a knob is added inside a panel?
body: <p>I want to add a knob to a node, but i want to make sure that it is always shows inside a specific tab. </p>
  
  <p>let's pretend that target node has two tabs, 'A', and 'B' that were created long ago.</p>
  
  <pre><code>target_node = nuke.thisKnob()
  taget_node.addKnob(extra_knob)
  </code></pre>
  
  <p>how can i make extra_knob be created in tab 'A' instead of 'B'?</p>
  
  <p>when i open the .nk file in a text editor knobs seem to have an index, but i can't find anything of the sort in the documentation</p>
