You should be able to define office-wide billing records and incorporate them into an offer, an offer template or a contract with a button if these differ from the office-wide employee categories. This would be useful if the office-wide rates have changed since the template was created. It should also be shown that the rates differ from office standards. It would also be ideal to be able to assign specific employee categories to such billing record templates (billing set 1 combines employee categories x and y).
