Can the stretch renderer use only pre-defined color ramps for display of elevation data?

I'm trying to display continuous-valued (floating point) rasters in ArcGIS Runtime v100.0 (for example, with values on the range [-2.5, 6.3] or [0.2, 0.44]. In the API Reference for the Stretch Renderer, the fourth parameter of the constructor is a ColorRamp object.

public StretchRenderer(StretchParameters stretchParameters, IEnumerable<double> gammas, bool estimateStatistics,
ColorRamp colorRamp)

This object seems to have only a Create method - which creates a color ramp of a predefined type and size.

public static ColorRamp Create(PresetColorRampType type, uint size = 256)

The PresetColorRampType enumeration has only the following types: -1 (not defined), 0 (elevation), 1 (DEM for screen display) and 2 (DEM, light-colored). Can I create a custom ColorRamp that I can use to display my floating point raster data? Any insights will be greatly appreciated!

At this point yes, but it's on our backlog as a future enhancement.
