Auditing Role (at time of action) for Case Status Change

Hi all,

Our only auditing requirement right now is to track changes to Case Status; easy enough.  Problem is our client wants to know the Role(s) that the User was assigned at the time of the change.  A snapshot of their Role(s) basically.  Is this possible?

Also, and a pet peeve of my OCD, the system is logging changes to Case that don't have to do with Status.  Our Audit History is full of records that say:

The fields changed by this action are not enabled for audit tracking.

How stupid is that?!? Anyways, How do I stop this from littering my Audit History?

Thanks,
