title: Modifying lists of lists in Robot Framework
body: <p>I have a nested list that I am using in Robot Framework.  I would like to change one item in a sublist at the Robot Framework level.</p>
  
  <p>My list looks like this:</p>
  
  <p>[ bob, mary, [june, july, august]]</p>
  
  <p>I want to change "july" to something else, say "september"</p>
  
  <p>Robot Framework will let me change 'bob' or 'mary', but if I try to insert a list, it is converted into strings.</p>
  
  <p>(Oh, I have tried to use the "Insert Into List keyword to insert a new sub list, and other List keywords, no luck with any.)</p>
