RRDI - passing current user in Report Studio

Hi,

I found the way how to use some current user data in RRDI Report Studio like these:

account.personalInfo.email (e-mail address)
account.personalInfo.givenName (First Name)
account.personalInfo.surname (Last Name)
account.personalInfo.timeZoneID e.g. EST
account.personalInfo.userName (login user id)

When I log in to Cognos RRDI portal, and go to My Preferences, and Personal tab, I can only see my email and userId retrieved from CLM.
So, my question is: How I can use the full given name (ex. John Doe) on report?
How can Cognos RRDI pick-up full name from CLM?
Because I am building some kind of reports where current user will be able to see only his work items and tasks for example.

Thanks,
