Multiple Sub Totals for Waterfall

Hi everyone,

I would like to make multiple subtotals for waterfall chart.

The result should display as the exam picture below.

1. I try to use the visualize of waterfall chart in Power BI and setting format of breakdown as below.

But It not work. It has shown subtotals every 3 bars.

2. I try to use the custom visual (Ultimate Waterfall) and setting format of subtotal as below. 

But It not work. It has shown only one subtotal (in the fourth bar).

Could you please suggest me to solve this issue?
