Data navigation between different hierarchies

[Rosanero4Ever]

Hi all,

I have a report which uses a dimension represented in DMR as follows:

All Regions	All Groups
Region	Group
Customer	Customer

So I can perform drill down/up starting from Regions or Groups until to the Customers.
If I reach a Customer starting from Region is possible perform a drill up to the Group changing the hierarchy?
I hope my explanation is clear
Thanks in advance for your help.
