Allow unbalanced nested combinations of measures and columns in Matrix

As of today, if I use several measures in a matrix and also use a field as a column, the matrix will show all the measures for all the values of the field.

We would like much more flexibility.

To allow nesting of columns and measures, but to specify what measure should be "splitted" by columns, and what measures shouldn't.

This will allow much more flexibility in matrix.

For example:

Here you can see that only Sales measure is "split" by "Year-Month" column, while all other measures are not.
