Hello,
In ArcGIS Desktop, Data Reviewer supports custom (user-defined) fields. This isn't currently available in Pro.
We find additional custom fields extremely helpful when reviewing and correcting errors since features are only identified by Object ID in the Reviewer Results table. It can be difficult to tell them apart, sort, or group them. We've added things like Street Name and Street Type (for our parcel, address, and street data). This helps us in several ways including - it's easier to work with more recognizable information and allows us to locate and work with features in the same area since they often suffer from the same errors and can be corrected as one group instead of one at a time.
