Use Forecasted EAC as a base in calculating Percent Spent through Project Process Configurator

Summary:

We use cost-to-cost or percent spent revenue recognition method for our client. We had to configure a Project Process Configurator (PPC) because of some exclusion rules we had to feed in, like exlcuding specific expenditure types in revenue calc. While configuring the PPC, we used "Calculated Planned Burdened Cost in Project Functional Currency ITD" as a base to drive percent spend calcs. This calculated attribute points to the approved Budget instead of the approved forecast. Is there are way to configure a PPC pointing it to the approved forecasted EAC cost rather than the budget?
