Time series forecasting AutoML Automatic featurization groupby specific column values

Question

Hi,
I'm training time-series forecasting models with Azure AutoML.

As far as I’m concerned, featurization techniques such as Normalization and Scaling or Impute missing values, are applied by columns.

Given that I’m dealing with time-series data, is there a way to apply these kinds of featurization using a group by some column values? Otherwise, I feel the transformations applied make no sense at all.

For instance, If I want to predict product demand from different stores, would be possible to impute missing values from one article given the median of that article (not the one of the column) modifying AutoML Automatic featurization? Or standardize the target values for each article separately?

Thanks in Advance.

@Marcrb Thanks for the question. "featurization": 'FeaturizationConfig' Indicates customized featurization step should be used. Learn how to customize featurization.
