Expression not to cut by a Dimension

[#1]

I have an expression with 2 dimensions.  I want the expression to cut by one of the dimensions but not the other.  I know with set analysis we can have it not filter by selections but is there a way to say don't cut by an expression?

I think you need the total qualifier with field list here, like using Customer and Product as dimensions and

=sum(total<Product> Value)

as expression will return the sum of Value per Product, so not regarding the Customer dimension.
