Export to Excel Issues

[Jenny]

We have just upgraded to 8.4 from 8.1.  My users heavily use the Export to Excel function in the Contributor app.  We have 4 levels to our e.List and they export at the 3rd level so they can see the roll up and the detail level.  In 8.1 they were able to append an e.List above another by using a saved report.  They are no longer able to do this.  Has anyone else come across this issue or have any work around ideas?

Thanks tons!
