Nested pages

Hi!
I would like to add deep nesting with the “Insert Pages” plugin..
I have found your reference to the v2.4 notes in the changelog.

Is there a way to do it with an option in the short-code? (Like nesting=yes)

Or, if the code in the changelog is the only solution… where should I insert the code and how can I make sure that it will work after new versions of the plugin, the template or WP itself?

Thanks a lot… for this great plugin!
