If I have an employee that is a hiring manager for a group of requisitions and a recruiter on for a different set of requisitions, is it possible to utilize Taleo to permit both using 1 user account?  

I can only see it being done with 2 accounts.  I cannot fins a combination of CSW, User Type, User Group that would facilitate this so is there some other functionality I am missing?

Thanks so much!
