Specifying that an Option requires another Option

Hi everybody, is there a way in CommandLine (I guess in a way similar to what is done with mutually exclusive properties) to specify that an option requires another option to be set? This is a short example:

        [Option('v', "verbose",
            Required = false,
            DefaultValue = false,
            HelpText = "Prints log messages.")]
        public bool Verbose { get; set; }

        [Option('o', "optional-operation",
            Required = false,
            DefaultValue = false,
            HelpText = "Performs an operation (a.k.a. \"does something\") in the code.")]
        public bool PerformOperation { get; set; }

        [Option('t', "time-limit",
            Required = false,
            DefaultValue = false,
            HelpText = "Requires option -o. Specifies a time limit for the optional operation")]
        public int OperationTimeLimit { get; set; }

In this scenario, one would want to allow command line arguments like -o and -vot but not -vt or -t for instance, since in the latter the option -t is specified without -o. Is this currently possible in CommandLine?
