Combined-superset-from-several-Wealth-Data-DataSets

Is there a simple way to create a large combined superset from several wealth-data datasets, which can then be executed with the StrategyRunner (or saved to the Datasets Folder)?

CODE:

public override void BacktestComplete()
{
   List<string> dataSetNames = new List<string> { "NASDAQ 100", "S&P 500", "DOW 30" };

   DataSet combinedDataSet = new DataSet("Combined Superset", DataSetType.UserSymbols);
   HashSet<string> uniqueSymbols = new HashSet<string>();

   foreach (var dataSetName in dataSetNames)
   {
      DataSet sourceDataSet = WLHost.Instance.FindDataSet(dataSetName);
      if (sourceDataSet == null)
      {
         WriteToDebugLog($"Source DataSet '{dataSetName}' not found.");
         continue;
      }

      foreach (var symbol in sourceDataSet.Symbols)
      {
         if (!uniqueSymbols.Contains(symbol))
         {
            uniqueSymbols.Add(symbol); 
            combinedDataSet.Symbols.Add(symbol);
         }
      }
   }

   DataSetFactory.Save(combinedDataSet);
   WriteToDebugLog($"Combined DataSet created with {combinedDataSet.Symbols.Count} symbols.");

   StrategyRunner sr = new StrategyRunner();
   sr.DataSet = combinedDataSet;
}
