Waterfall Chart challenge

[Anonymous]

I have a waterfall chart that is created dynamically based on user inputs.

The user selects the start point and endpoint which have to be compared to each other through slicers inputs and the waterfall chart displays the variances in between. Is there any way I can fix the starting point to be displayed as the first bar and the endpoint as the last bar? (Sorting alphabetically won't work in every case.)

Where?  in Power BI?  How?
