Original title: "RadColorPicker should have a built in custom colour selector"

I'm aware that I can add a custom colour selector to the RadColorPicker myself and an example is given in the Telerik WPF demos, but rather than having to implement this myself, I'd really expect this to be built in so I could just set a ShowCustomColors="True" flag and it'd be done. Other UI control vendors I have worked with have supported this functionality without making me do so much work.
