Crew Manager - Data Export that would include crews deleted/removed from perspective

There is currently no way (even with the audit report) to find out if a crew was once in a perspective but is no longer; for example the crew was deleted, an attribute changed that removed them from the perspective, etc. The only way to find that information is do an Activity Report by person and the person running the report may not know who made the change or even if a change was made. For regulatory compliance, our utility needs to be able to track our crews and if a crew was removed in error, we need to be able to locate and identify that data.
