Hi Brittany,
I reckon setting the email Subject as ItemKey prior to sending the items to the WorkQ should fix your problem nicely.
That said, you may want to check with your local GDPR officer to see if it would be allowable to have the Subject visible for all to see in ControlRoom. In my place of work it is definitely not, but obviously that depends on what kind of data your Subjects may contain.
