SAP BO Compare Reports in Design View

Hi,

I am new to SAP BO. I have an immediate task and am seeking out today hoping that someone can point me to the right direction. I have thousands of reports accumulated over years. I can group them together. What i am trying to do is to understand if there is a tool within BO admin suite that allow me to compare objects, filters, ect of these reports. I am trying to understand what the differences are in design mode. I can manually open them up but this effort is going to take months.

thank you very much.
