Thanks Don. It is a really cool tool. I took a look into the code and it helped a lot!
I found the answer:
.ReportClientDocument.ReportDefController.ReportObjectController.GetAllReportObjects();
However I am not able to rebuilt the project since many of the reference objects are missing.
i.e.:
The type or namespace name 'EromPageSettings' does not exist in the namespace 'CrystalDecisions.ReportAppServer.ReportDefModel' (are you missing an assembly reference?)
The reference version is 13.0.2000.0 and its location is at
C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet\CrystalDecisions.ReportAppServer.ObjectFactory.dll
