Can we use table validated value sets in Payroll Cost Allocation flexfield?

Summary:

When we use the same value sets defined in GL accounting flexfield, users can see parent values in payroll costing pages when selecting segment values for payroll cost allocation flexfield. I know we can use table validated value sets if we include project segments in cost allocation ff, but has anyone used table validated value sets using fnd_flex_values to filter only child segment values from GL accounting ff value sets?
