Redmine

We currently have Redmine 2.4.1 installed on Ubuntu 13.10 and we have encountered a road block in one of our requirements that we have not been able to find an answer for in the forums. We need to be able to compare the values of the same fields on different projects; for instance, we have two projects with the same tracker that contains boolean values for all of its fields and we need to note the differences or variance existing between these two projects. We have not found any plugins that satisfy this need and nothing regarding the subject in the forums. Any help is greatly appreciated.
