Drill through doesn't work from the total cell of a matrix visual. Please add this as well

Within a Matrix visual, you can click on each cell and you will get the drill through menu. This works on row and column totals as well, but you can't do it from the main total cell, i.e. the cell that doesn't filter on either column or row attributes. Please remove this constrain.

Why? From a end user perspective of a report, they might also be interested to view a more detailed data-view using the (in most cases) hidden "drill-through" report, this even for the totals within a Matrix visual.
