There is the Diagram Tree which may help. Press F8.
I don't do this, but I believe the dia is xml, so there is a way to get
into the guts of the file using xml tools.
If this isn't helpful to you, please reply with further elaboration and
others will add to my comments.

For example, if there are many classes objects in the dia file, so
that i can see what i have drawn and won't duplicated the same class
objects
