Output array of results

Instead of returning hard coded results one by one like;

[Output("Result #1")]
public IndicatorDataSeries Result1 { get; set; }

[Output("Result #2")]
public IndicatorDataSeries Result2 { get; set; }

[Output("Result #3")]
public IndicatorDataSeries Result3 { get; set; }

I want to return array of results of any size like;

[Output("Results")]
public List<IndicatorDataSeries> Results { get; set; }
