Named Users in BO

Good Morning,

I am wondering if anyone knows a way to determine how many users are currently set as 'Named Users' in the system without actually going through each user individually and checking. Is there a way to do this through CMC or somewhere else in BO? Any help is appreciated!

Thank you,

Tiff
