When I open a defect and assign to a Sprint it gets displayed in the Iteration Plan's Planned Items page, but it only shows the Summary, Work Estimation, and Priority fields in this view

We would like to also display the unique defect Number assigned to each defect in this view rather than having to open each defect to see the number assigned. Our team refers to defects by their numbers and not based on what their summary is.

Is there a way to configure this?
