Conditional formatting on dynamic formatting options

Hi,

I would like to know if, using custom visuals API 3.5.1, it is possible to apply conditional formatting to dynamic formatting options. By dynamic formatting options I mean options that are added to the formatting pane as the user adds values to the visual. For instance the data colours that are added to the Funnel visual:

As you can see here, conditional formatting is available only for the (statically named) "Default color" and not for any of the dynamically added values.

Currently, my capabilities.json file contains this for data colors:

        "dataColors": {
            "displayName": "Data colors",
            "displayNameKey": "Visual_DataColors",
            "properties": {
                "fill": {
                    "displayName": "Data color",
                    "displayNameKey": "Visual_DataColor",
                    "type": {
                        "fill": {
                            "solid": {
                                "color": true
                            }
                        }
                    }
                }               
            }
        },

And my settings.ts file contains this:

export class dataColorsSettings {
  public fill: string = null;
}

When I enumerate my data colors object instance, I add any dynamically added values like so:

   private enumerateDataColors(valueColumns: DataViewMetadataColumn[], instanceEnumeration: VisualObjectInstanceEnumeration): VisualObjectInstance[] {
        if (!(<VisualObjectInstanceEnumerationObject>instanceEnumeration).instances) {
            return;
        }

        let instances = (<VisualObjectInstanceEnumerationObject>instanceEnumeration).instances;

        for (let v = 0; v < valueColumns.length; v++) {
            const displayName = valueColumns[v].displayName;
            const selector: ISelectionId = this.host.createSelectionIdBuilder()
                .withMeasure(valueColumns[v].queryName)
                .createSelectionId();
            this.addAnInstanceToEnumeration(instanceEnumeration, {
                displayName,
                objectName: Visual.dataColorsPropertyIdentifier.objectName,
                selector: ColorHelper.normalizeSelector(selector.getSelector(), false),
                properties: {
                    fill: { solid: { color: this.viewModel.valuesColor[v] } }
                }
            });

            let obj = {}
            obj[displayName] = VisualEnumerationInstanceKinds.ConstantOrRule;
            instances[0].selector = dataViewWildcard.createDataViewWildcardSelector(dataViewWildcard.DataViewWildcardMatchingOption.InstancesOnly);
            instances[0].altConstantValueSelector = null;
            instances[0].propertyInstanceKind = obj
        }

        delete instances[0].properties['fill'];

        return <VisualObjectInstance[]>instanceEnumeration;
    }

While this does add a correct looking propertyInstanceKind object to instances[0], no conditional formatting options appear in the formatting pane.

Since I have not been able to spot a native visual that has conditional formatting for dynamically added values, I'm ready to assume it's simply not supported at the moment. 

Can it be done?
