Display all levels of an hierarchy

[collierd2]

Hello

I've spent quite a bit of time trying to work out how to do this (C8.2)

Using report studio, i've created a report
The report is a list report with a customer hierarchy in the first column and various sales figures alongside it
The customer hierarchy goes: region -> branch -> sales rep -> customer
When an individual drills down on this hierarchy, it displays the previous level as part of the list report (top left)
How can I display the full hierarchy?
That way, when an individual has drilled down to customer, they not only see the sales rep, they see the branch and region that the customer belongs to as well
I would preferably like to see this in an 'header' section

Thanks

Damian.
