Add a "business" column to employee's entitlements page

Hello everyone,

In the web portal, in the page of an employee's entitlements, there is a column named Entitlement where values may be the names of active groups like oim.lab\Groups\tech1.  
This is ok but I think that for a business manager/user that name is not so meaningful as the name of the associated service item "Alfresco".
Is it possible to add as first column a column named product (or item) with that names?
