debugger - copy nested var declaration vs copy var name

In the debugger it is possible to copy the value of any item as well as the name.
When working with Drupal 7, more often than not you are dealing with n levels of nested arrays and objects.



In the above example it would be a lot more useful if "Copy Name" would not only copy "0" to the clipboard, but instead cover the full nesting:
"$form['revision_information']['#attributes']['class']['0']"

Is something like this already possible in PHPStorm 6/7 ?
