willard800,
Sorry, no can do. I think the reason it's not available as a timescale value is because it doesn't make much sense. For example, let's say you have a 4 week task and the timescale display is in weeks. Is there any benefit to showing there are 6 hours or remaining work in week one, 10 hours in week two and so forth? It just doesn't make sense because you don't know how much actual work will be performed in those weeks. What does make sense is the cumulative remaining work and that value IS available in the Details.
Hope this helps.
John
