Test Execution Assignment Gadget: is there a way to make Unassigned show up?

For what it is worth, I executed a test case w/o assigning it and because I didn't assign it before execution it still doesn't show up as covered by me. (an intentional action/test)

I understand why (Test Execution Assignee and Executed By fields are different), but it make it difficult to track down the data inconsistencies.
