enable Drillthrough for multi-level Sankey

[abakes21]

Hi,
I've made a multi-level sankey and am trying to add supporting visuals for the visual. I added an index column in power Query. However, it looks like the Sankey visual does not support drillthrough. Is this something that may be added?

Thank you!

All the best,
Andrew
