Drill down on Hierarchy in Legend

Dear,

I've build a report with a 100% stacked bar chart.

The chart is build with the Month on the X-axis and the Revenue on the Y-axis.

I've created a Hierarchy of the products and their underlying categories. It's a Hierarchy of 5 levels.

I have the top Hierarchy level as the legend. I would like to select a part of a bar chart and drill down on that to the next level in the product category Hierarchy.

However, currently this is not possible as the legend does not allow more than one Hierarchy level. Besides that it's not possible to Drill Down on legend.

Could this be build in future updates? it would be very helpfull

Kind regards.
