Tabular calculated member

Hey everybody,

i hope some one can help me with that problem.
Tabular mode and 2 Tables: fact_salesinfo, dim_version
The Tables look like that:

Fact_salesinfo:
SalesId,versionid,Net Sales, cost
1,1,100,90
2,2,110,80

dim_version:
versionid,versionname
1,Actual
2,Budget

In Multidim mode it was possible to add a calculated member to Version which said:
[dim_version].[versionname].[Actual] - [dim_version].[versionname].[Budget]

Now i was able to calculate Actual - Budget for every column in my Fact Table.

My Question is:
Is there a possibility to do the same thing, since i have a lot more Columns in both tables and wouldnt like to create every single combination in the version table for every column in the fact table.

Thanks a lot.
