Horizontal funnel without reshaping data into stages

Hello, I am trying to produce a horizontal funnel chart. My data is in this type of format:

I am currently using the custom Horizontal Funnel visual by MAQ software  but I find that the data needs to be in the following format for it to work:

While it is possible to replicate this format by unpivoting my data, I want to avoid this if possible. With the default (vertical) Funnel visual in Power BI it is possible to just drag the columns I need to the Values section in the order that I want them displayed. Is there any way to do something similar to create a horizontal funnel?
