I have thought about requesting the same feature previously but realised that some authors who had to post multiple code fragments to explain their code would be disadvantaged by this approach. In this instance, instead of having the ability to space and title code fragments accordingly, the entire section would appear as one long block of code instead of separate parts. The change in title however is an excellent suggestion.

You should however be able to edit the node - If you go to your node, there should be a small "edit your code here" underneath the table border around your code block.
