Allow cumulative possible values and properties configurators

[cdprete]

Hi.
At the moment, the methods with[Numbered]PossibleValues and withPropertiesConfigurator only apply globally, aka to all the possible choices.
It would be nice to be able to to define the possible values in a cumulative way and also pass the configurator to just that subset of possible values so to render them differently.
I know I can print all the properties manually and use an int reader as workaround to have the same behaviour, but it's quite ugly.

Does this feature make sense to you?

Cheers
