Can you use Wildcard in cube formula?

[mythos2112]

I am trying to get at some specific information in a cube. The structure is

Code > vendor > product > source in the field I'm cubesetting. If I were looking for all orders by a particular vendor, I'd do something like

{

.[Vendor].[VendorX]}
 
However, I'm actually looking for all orders for the product Product Y, no matter what vendors that product falls under (will be almost every one of them), Products are set under all the vendors. So, since I don't want to list the thousands of vendors, I need to wildcard it like 

{[Code].[Vendor].
[*].[ProductY]}
 
- but that doesn't work.

I intend to use this line in a cubeset, so it ends up being =CUBESET("cubename",{[Code, etcetera]},"Product Y")

Is there a way to make this actually pull the data I'm looking for? I cannot change the OLAP cube itself; this has to all be done via Excel if it can be done.

Many thanks!
