Setting Maximum and Minimum Value for GradientColorPalette

I am using a GradientColorPalette to apply a color mapping to a WaterfallRenderableSeries3D. It appears that the gradient positions determined by GradientColorPalette are dynamically set based on the maximum and minimum value displayed on the chart.

I would like the gradient positions to be determined by a static value, similar to how setting the “Minimum” and “Maximum” properties of a HeatmapColorPalette class works.

Is there a way to do this using GradientColorPalette?

Thanks
