Can we use forecast.gts function and include forecasts from a state space model

[trickster]

each and every time series in grouped time series are forecasted separately in forecast.gts function. If I have forecasts from a different method (State space method) for both top and bottom levels, can I have them included in the forecast.gts function?

Use the combinef() function if you already have forecasts.
