given 2 options, can the second option default value 'point' to the first option value?

hi all
I have a case where given the folliwing options:

  @Option(names = { "-in" }, description = "number of inputs. defaults to 1", defaultValue = "1")
  private int in;

  @Option(names = { "-out" }, description = "number of outputs. should default to inputChannelCount value", defaultValue = "???")
  private int out;

i need the default value of out (in case not explixitly given), to be the caluculated value of in (either in's exlicit given value or its default value)
is there a way to achieve this?
thanks

I haven't tried this, but one idea is to have a custom default provider, something like this:

@Command(defaultValueProvider = MyDefaultProvider.class)
class MyCommand {
  @Option(names = { "-in" }, description = "number of inputs. defaults to 1", defaultValue = "1")
  private int in;

  @Option(names = { "-out" }, description = "number of outputs. should default to inputChannelCount value")
  private int out;
}

class MyDefaultProvider implements IDefaultValueProvider {
    public String defaultValue(ArgSpec argSpec) {
        if (argSpec.isOption() && ((OptionSpec) argSpec).longestName().equals("-out")) {
            return argSpec.command().findOption("-in").getValue().toString();
        }
    }
}

thanks I will take a look at that. marking as answer as you are the maintainer and probably know best. :)
thanks
BTW, maybe its not a bad idea to have in the future a default provider config in the option level (as oposed to the command level)? thanks
