Notion 4 - Indent first system in score and/or in the parts?

How do I indent the first system in the score and/or in the parts? I did a search of the forum and only found one thread from back in 2010, which seemed to say this wasn't possible. I'm hopeful that it has been made possible in the interim because it's an important issue for proper layout of the score and the parts.
Am I missing something?
