Waterfall Breakdown Static instead of Dynamic

Hi Michelle1608 ,

Sorting by break-down in a customized order is not currently supported in power bi, which only supports ascending or descending sorting, and that is by design.

If you would like to suggest  feature improvements, you may  vote the idea and comment Microsoft Idea (powerbi.com) to improve this feature. It is a place for customers provide feedback about Microsoft Office products . What’s more, if a feedback is high voted there by other customers, it will be promising that Microsoft Product Team will take it into consideration when designing the next version in the future.
For more details on the waterfall model you can refer to this official document:

Best regards
