I would like a way of being able to validate and QA AAM audiences within Audience Manager. With most campaign tools such as Adobe Campaign, marketeers have the luxury of being able to output lists and quality check them against what is expected in the segment build or brief.
At a high level, the differences between *.sync and *.overwrite files when it comes to uploading CRM data (Offline traits) to AAM can cause inaccuracies in segment builds. Being able to view underlying data to see what should or should not be there, would ensure better accuracy within AAM segments and hopefully yield better campaign performance.
This would also help to eliminate human error when building complex segments
