Cross validation with stratified folds

There does not appear to be a way to stratify data in ML.NET, is this likely to be implemented anytime soon?

Say I have data that has an uneven predictor field split 90% / 10%, I would like to cross-validate the data with k folds so that each fold will produce an even predictor split of 50% / 50% (or any desired split setting value).

This does not seem possible yet but is a major feature that is required as part of ML modelling.
