Reporting on owner assigned to a test case in a test set

On a test set page, in the list of test cases you can select an owner for each test case. 

How is this function used, because it is not linked to the ownership of the test case itself, nor is it linked to your personal page to show your assigned test cases, nor it is possible to have it available in a report. 

So how can this be used? 

We would like to have it visible in the dashboards, so you can see which test case is assigned to which person and what the progress is on those test cases (execution state) 

Thanks
