Financial Plans - Can add burden on top of the cost

Is it possible to add a burden from a schedule on top of a cost calculated in a financial plan?

i.e. 

John Doe 40 hours x 10/hr = 400.  Now apply a burden schedule to this cost within the financial plan.

I see where in plan settings you are able to add the burden schedule/cost schedule, but when I generate, the burden isn't applying so possibly I am missing something.

Kindly advise.

Thanks in advance
