Agreed with urmas. We would LIKE to be able to report on past actuals vs allocations, but because of this limitation in the tool to preserve past allocations, those reports are unreliable and essentially useless. We will occasionally look at a very short time period, like past 3 months for example), and just understand that it still can't be guaranteed to be accurate, but atleast gives a ballpark. Ideally, I would think changing the default should create a new segment from that date forward, leaving the past in tact.
