How to Differentiate Assignments when Employee has multiple assignments aside from Business Title

Summary:

We're aware that if an employee has multiple assignments, the Business Title field will be visible on the Goal and Performance pages. After testing a few scenarios, we discovered that if you have 2 Assignments with the same job name/business title, it will display 2 values of the same business title name, therefore unable to quickly differentiate the two. Is it possible to have a different field aside from Business Title to specify the assignment? If not, how can we differentiate the assignments if it has the same name?
