Is it possible to add same objects (measure) two times in Webi query layout ??

For our project requirement , We need to implement logic :

Query 1 : A, B

Union

Query 2: A, B

Union

Query 3 : A ,A

Union

Query 4 : A,A

Note: We wanted to implement this logic without using custom query & without creating two objects with the same definition at the universe level.

Is there any other way to achieve this?

Pranay.
