Customization of User list Field in HP ALM

Hi All,

I am facing an issue in customizing the user list field in HP ALM.

Normally the user field contains the UserId and UserName column. But I want to add, one more column "Group Name" in the userlist dropdown.

Can anybody suggest or provide the solution to achieve this in HP ALM.

Please find attached the screen shot of the userlist field.

Thanks and Regards
