You can track changes in the audit by adding the page list property in 'pyTrackSecurityChanges' data transform. Also, you can customize the string display in audit tab, by editing ChangeTrack_Change field value and saving to your ruleset. But as per current design, I don't think you will be able to append another property value (i.e., Name) in the audit history.
Apart from the implementation mentioned above, you can also look at having an on change event on the drop down where you can pick details from the Primary page(the active row of the grid where the status change happens)and record the change using a history-add method
Even in this case you can make use of a similar approach,You can use a property where you write the change that has happened( in your case the text for audit) on change of the drop down and make use of history-add on postactivity of the flowaction.
