Isolating rules: Topology Rules Check

We have a Cadastral Topology with 17 topology rules and it has 5 participating feature classes for the whole County.  Each feature class contains between 24,000 to 2.3 million features.  Every year I need to run and extract errors from just two of those rules ???AOI must not overlap??? and ???AOI must not have gaps??? for the whole County.  In the past, I would export the AOI layer to a new file geodatabase, create a new topology with just those two rules, validate and I would have my list of errors.  I also use the ExportErrors.dll to create a new ???error??? feature class to give to our editors for clean-up.

We want to know if Data Reviewer can help us so that I do not have to keep exporting the AOI and working off of the main database. I am currently looking at using the Data Reviewer ???Topology Rules Check??? on a test database that has the 17 topology rules implemented. Everything seemed to be going well and it seemed like what I wanted, but then I found out that I needed to validate my area before I ran the check.  I enabled the ???validate topology??? check box, but it doesn???t seem to validate just the two rules that I specified, but it would validate the whole topology, meaning all the 17 rules. (*Note, ArcMap froze when I ran the check).

I feel like I am back at square one.  I would like to get all the County-wide errors associated to only those two rules, but I want to avoid validating the whole County to do so, because trust me, it will take a long, long time???  It would also be nice to run this process using Data Reviewer so that we can keep track of editing and the QA/QC of these errors.

What are your suggestions and are any of these needs an enhancement request?

Thank you.
