Custom Privilege Levels - TACACS+ - Port Security

[FrozenBits]

I'm not sure if I'm posting this in the correct "series." 

Our enterprise uses a wide range of ProCurve devices from 2610-24-PWR switches to 5412zl models.  Currently we use Cisco ACS 4.2 as the server to administer TACACS+ authentication to our devices.  I'd like to start creating accounts with only the ability to perform certain commands on the switches.

For example: I'd like to give the IT Helpdesk Techs the ability to manage port security.  Is there a list of privilege levels for ProCurve devices?  All I can find is "Level 15 is manager, Level 14 and below is Operator." 

Is that as granule as I can get with which commands they can run under any privilege level?
