Ability to link a Master Feature to a Feature by entering the Record Number Merged

Currently when trying to link a Feature to an existing Master Feature/Epic, Initiative, or Goal, the search box does not allow for entry of the record number. Instead, the user must type the title of the Master Feature/Initiative/Goal to link it to the Feature.

This is a bit unintuitive as you would expect this field to act similar to a Search box which allows searching by record number and title, but record number is not supported. It would also make the process of linking records easier as I would only have to remember the record number rather than the exact title of the Master Feature/Epic.
