The Edit Metadata module in Azure Machine Learning Studio is designed to modify the metadata of existing columns, such as changing data types, renaming columns, or marking columns as features/labels. It cannot add new columns to a dataset. The community discussion strongly supports this, with the top-voted comment (30 upvotes) stating 'Edit meta data cannot add a new column, it can change properties of existing columns.' Other comments note that adding columns requires different methods like SQL transformations, Python scripts, or the Add Columns module. Since the requirement is to add a new feature column and populate its values, the Edit Metadata module does not satisfy this requirement.
