I cannot believe this is not fixed.  What a painful experience.  We are new to projects and excited to have this level of profitability visibility on our business.  But we are in the middle of our work with dozens of clients and trying to institute this in our business requires assigning paid invoices to new projects to get this set up to move forward.  I'm very interested in a fix for this and none of the workarounds are acceptable.  What a painful surprise that this is still a problem after reading through all the requests from QBO users.
