Creating a parent dimension within an existing UD Attribute
Hi
We have set up a line of business attribute in our UD3 dimension based on cost centres. It has become clear that in several reports we need to aggregate some of these members. I think the easiest way to do this would be if we could introduce a new layer between the current parent and children. My questions are a) is it possible to do this and if so how? and b) how would this impact reports that are already in circulation?
I have tried to illustrate what I'd like to do in the picture below.

Thanks
