Content Expiration tasks not automatically assigned to Content Owner

Summary: Current implementation of Knowledge Advanced uses the Content Expiration task to generate a task when the content is 7 days from expiring. This process is working. But all these tasks are Assigned to Unassigned as opposed to assigned to the content owner (as we would like). We can modify the assignment to the Content Owner, but only as a manual action. I can't find anything within any of the settings that seem to control this.

Have any other users experienced this?

I want to make sure if this is a setting that needs updating, a ticket that needs logging or an an Idea that needs suggesting
