Have Idea categories available and persist through to promoted Feature Merged

I would like the ability to add the idea categories field to feature, so categories selections at ideas are visible and persist through to its promoted feature. Further the linkage should be bi-directional so if the value is changes in either idea or feature it would persist through bi-directionally.

To many larger products, categories often informs which engineering team the feature is routed to. Today we have to use reporting or click back to the feature's idea to view the selections. It would reduce touch time if we could just make this field available right in the feature card.
