option 82 config help

[project722]

I wanted to clarify a few things on my above post. The O82 logging config
above is set globally. In order to accomplish my objective while still
retaining the functionality of the config above, would it be possible to
simply add a new logging config for option82 into the specific subnet or
pool declaration where I want the new logging to occur? I think that may
work and over-ride the exisitng 082 config, just for that one subnet/scope.
