Multiple item (inventory, purchased expense to project, G/L) to a PO AX 2012

We are transitioning from Dynamics GP to AX2012 and cannot seem to create the same functionality in AX that we had in GP.

In Great Plains we were able to create a single PO and include puchased items to a project, purchased items straight to the G/L and inventory items.  We have not been able to do this in AX.  Does anyone know if this is possible?
