You really should figure out how to do this ASAP because it makes the Projects view rather misleading. Almost all of my projects are purely labor and if you switch it to the time costs view its almost guaranteed to show a negative profit because we've tracked out vendor labor hours _and_ paid them which counts as an expense.
So that view seems entirely redundant if you can't actually draw down on what the project thinks is outstanding expenses.
This seems like a fairly half implemented feature at this point.
