One of the massive time savers in Unity is the ability to export your scene from your DCC and have Unity automatically import it as a prefab. This contains vector locations and a list of separate meshes from the DCC.
In short it allows you to drag and drop your entire scene representative of what’s in your DCC and move bits / remove what you like. Instead of having hundreds of models which you have to re-build from scratch one by one.
It would be a massive time saver, could you please add the feature request?
