We would love to be able to track the number of people who have ever been assigned to a certain fundraiser over a period of time. We use inactive relationship types to suppress the old relationships from web view. In doing this, they are excluded from the API. It would be great if we were able to access these inactive historical relationships via the Fundraiser Assignment List endpoint.
This would definitely be better than the way it is now, and even better, make it a filter so we can narrow down to assignments that have been reassigned to a different fundraiser within a set period.
