PJM Parameter Setup

I would be grateful for any assistance with an issue that we are experiancing when trying to set up a new organisation for EAM.  What we wanted was some of the costs to go direct to Projects and others direct to GL.  We can set the GL posting option to manufacturing to achieve this but on the account option we do not have the option of selecting Use Auto Accounting.  This means that whilst our GL costs are codes correctly our projects costs are not.

Is this something that we should be able to achieve and if not how can we get around our coding issues?
