Insight reporting - Comparing two fields

Okay this one might be complicated.  I'd like to do some comparison of data in our eloqua instance.  Does anyone know of  a good way to use insight reporting to compare two fields? For example: if the account and contact zip code don't match I want the results to come back in the report.

In the sample below I'd want to see the record come back showing the line with zip code 2909 LM.

Thanks!
