Hierarchies in Excel OLAP cubes

Do any of you know if it is possible to use predefined hierarchies when I report data out of Excel OLAP cubes? I have a text file with four dimensions...

Time
Measures
Organization
Scenario

Organzations and Measures are predefined hierarchies and I want to "view" data through these hierarchies.

If you have an OLAP cube and you connect to it through excel then you will be able to view any hierarchies that are defined.

These hierarchies will have drill through capabilities and will function based on the definaitions behind them in SSAS.

Edit: To generate a heirarchy that is not defined in SSAS will require a lot of time and manual groupings. This is better performed on the back end.

Ok, thank you. I use OLAP-cubes based on Essbase and make my own hierarchies there and view them in Excel, but do you know if it is possible to create hierachies in Excel's OLAP-solution. See a link below. One can create hierarchies based on the data itself, but I can't find out if it is possible to pre-define any.
