How to select an entire stacked column (all series) in a Perspective XY Chart?

Hello all,

I have a situation with a Perspective XY Chart where multiple series are stacked on top of each other to form a bar chart.

The current behavior is that clicking on a bar only selects that individual series' data point. I want the selection behavior to highlight the entire stacked column (all series within that category) simultaneously.

Knowing that the XY Chart uses amCharts 4 under the hood, is there a specific property structure, a PROPS configuration, or a clever way to handle this via event scripts? Thanks in advance for any guidance!
