The Direct Cost Analysis report will get you very close to what you are asking for. It prints the Original and Current Estimated cost for each job estimate, a percent complete and adjusted Current Estimated cost, the Total Cost Incurred, and a difference between Estimated and Actual Costs incurred. The report can be filtered to select only those estimates that have a certain % variance, and can be based on Total Cost, Unit Cost or Units.

I think the difference in what you are asking for and what this report provides is in the 'Adjusted Estimated Cost' (based on % complete) being compared to the Actual Cost incurred, rather than the 'raw' Current Estimated Amount.

Hopefully this may be useful in the interim.
