Lack of PCM functions (or I´m missing something?)

[ATVBrasil]

I´m not able to find basic functions on PCM like:

 1) Enable/Disable a Switch Port

 2) Change a port speed/duplex settings

I know that the #1 can be done by Switch Live view, but this means I need to have an user for my operators on the switch and I lost the nice Audit Log that is present on PCM. Our main goal is to have all the basic functions (done by Layer 1 team) thru the PCM with audit log, so that way we can track who and when do that change. But this 2 basic functions missing on PCM is very frustrating.

Or I´m missing something???
