Allow import of features from multiple products at product line or business unit level

As a curator of many products, updates often need to be made to features in different products at once. I would like to be able to include the product and/or product line as a column in the import so that the new features and feature updates can be applied across the products, streamlining that workflow. 

I feel that this would benefit many products managers who look at more than one product at a time.
