Only need choose dimension "Scope"

Hi

As our consolidation report,  we need choose the dimension "Scope" and the corresponding dimension "Entity"  member.  Like below:

Scope:                                                                               ENTITY:

            World                                                                                                             World

Asia         Europe     Africa                                                                      Asia          Europe      Africa

The Scope and Entity have the same strucure,  if user want to see "Asia"  report,  it need choose Scope-Asia and Entity-Asia twice. In order to reduce user manual activity,  by using macro,  when user choose Scope-Asia,  Entity's member automatically be changed to "Asia".

Now, we found the solution make many troubles.

I think our problem is common, so do you have the best practice for it.  Thanks.

Regards,
