Salary Grades and Custom Dimensions

Summary

We have a custom dimension that is required to create a unique Job Grade salary value, but we don't see it in the OEP_WFSC cube

We have a listing of job grades shown in the "Salary Grades" webform, and until recently we thought that the Entity member shown in the page would be good enough to make the salary values assigned to those jobs unique.  We now know that we need to pull in our Business Unit dimension to properly assign the different salaries (one entity/job combination can exist in multiple BUs).    We don't see that the custom BU dimension made its way to the OEP_WFSC database.   Is there a way to add this dimension to the Salary Plan form/OEP_WFSC database?
