Blank out (unassigned) in Assigned To column

Blank out (unassigned) in Assigned To column

Currently, if a request is not assigned to a technician, the word "unassigned" is displayed in the column. I would like to see an administrative option to either display "unassigned" (as it is now), OR completely "blank out" this column. I believe it is more eye catching, as is to say, easier to see which requests are not assigned to anyone, if the ASSIGNED TO column is BLANK.
