detail view zone

Hi,

I am trying to find zone of detail view on drawing.
My focus is to replace label on parent & I am thinking to replace that with note(with detail & zone information),
but if i have label selected(while creating detail view) , then in my parent view I have a leader pointed to that particular detail & replacing with note will only place note without leader.

Please suggest/ some sample code.Hope you are getting my point.
Thanks
