Option to Remove Underline from Matrix Header on Row Selection

In Power BI Desktop, when a row is selected in a matrix visual, an underline appears under the common column header. This visual cue can be distracting in certain report designs and is not always desirable.

Feature Request: Please provide an option in the matrix visual formatting pane to disable or customize the underline that appears under the column header when a row is selected.

Use Cases:

• Financial reports where visual consistency is critical
• Dashboards with minimal interactivity
• Embedded reports where selection behavior is not needed
