Returns the individual cashflows inside the requested bucket window for the holdings of the specified
portfolios, annotated with the source (Instrument, Transaction or SRS) that produced each cashflow.
            
The drill-down returns the complete resolved stream, including transaction-sourced cashflows, which
bucketed responses using the (default) InstrumentCashFlow representation exclude. To reconcile the
drill-down against such a bucketed response, first exclude rows with a sourceType of 'Transaction'.
