Allow for consolidated reporting that shows actual time entered (from timesheets) for historical periods and future resource forecast (from resource allocations) to see a full revenue forecast for a period of time.
Example: If I run a report on 4/15 with the goal of seeing the revenue forecast for all of April, I should be able to see all timesheets entered from 4/1-4/15 and all future resource allocations from 4/16-4/30 to get a full picture of the revenue for April.
