How to show description of activity while adding it into Timesheet



I am using PPM 9.20. While adding the activity for work item in the Timesheet, it only displays activity name coloum on the screen from where we can select the activity.


Is there any way to show description coloum also along with the activity name? Any validation name which can be customized to achieve this.


Any help in this regard would be much appreciated. Please let me know if you need further details.
