We have this virtual cube that has a dimension that is in common with
several cubes. What we need to happen is to create a virtual cube
bringing in several of the dimensions unique to each cube. This is not
a problem, the problem is what we would like to see happen is when we
make a change to that unique dimension for all the data from multiple
cubes to be updated based on the common dimension and all the
measures.

Hopefully this makes sense, help is needed...
