I hope someone can help me out in this one.
Is it possible to create a report that gives list of all the objects in the BO universe and below each object it gives the list of reports that use this object.
OBJ1
Report1
Report63
Report91
OBJ2…so on so forth.

Take a look at the following link:

This handy utility written by Dave allows you to see which objects are used in a report. It can scan all your reports if you download them to your local drive.

This thread is discussing the same thing, and offers other alternatives for consideration.
