UWL Modification Roles and profiles

Hi,

I have to modify an existing UWL to add a new custom column, so i've read some threads and i have pretty clear what I should do. The problem is that I need to access to the menu System Administrator-> System Configuration->Universal WorkList & Workflow->Universal Worklist Administrator and I don't know what role or profile do I need to add to my user to have access to this place.

Could you please help me on this point?

Thanks in advance,

Regards,
