Add option to pass list of columns into adjust_column input of CrossColumn transformers #237

Open Decima2014 opened 2 months ago

Currently the CrossColumn transformers like CrossColumnMappingTransformer can only be applied to a single column as opposed to most transformers that accept a list of columns.

I have come across a project in which I would have liked to use the same cross column transformer applied to a long list of columns which would have made these steps a significant portion of the pipeline steps.

Can we instead modify the adjust_column input to be adjust_columns and loop through these within the transform function?

Worth waiting for these two before picking up this one PR1, PR2
