title: Can you have automatic numbering indexes hierarchies?
body: <p>I am wondering if it is possible to have multiple indexes similar to the picture in which one of them (second level in my case) counts automatically?</p>
  <p>I have the following problem that i have data which needs to be updated repeatedly and the data either belong to the category &quot;Math&quot; or &quot;English&quot;. However I would like to keep track of the first entry, second entry and so on for each category.</p>
  <p>Now the trick is that, I would like to have the second level index count automatically within the category, so that every time I add a new entry to a category &quot;math&quot;, for example, it would automatically update the second level index.</p>
  <p>Thanks for the help.</p>
