Future data (forecasts) and PI Integrator for BA not providing modified forecasts

Forecast data is just that, forecasts that can change. Let's say hourly forecasts for the next 3 days is published every hour. This means, there is a potential for hourly forecasts to keep changing/overwriting forecasts. PI BA Integrator which publishes diffs after the initial run - in this case an AWS S3 target are not showing updated forecasts. We are losing this info. Is this a feature not implemented in PI Integrator for BA or is this specific target not supported with future/forecast data?
