Future Regressors for AI Forecasting ETL

It would be really beneficial to be able to add future regressors to the AI Forecasting Task in InMemory. So the same way we add Promotions or Low Stock regressors to the historic data that we import, if we could also add future promotions, estimated price increases, weather predictions etc. into the AI Forecasting task as regressors that would effect the forecasted values outputted from the script.
