Further Identifier on nominal accounts to help with screen selections

I come across this regularly when implementing new sites that when it's a new nominal structure the staff don't tend to know the codes immediately and click on the drop downs be it in any of the available screens and get presented with the full nominal structure. Can some sort of nominal identifier be added to define sales, stock, purchase. Meaning on a purchase invoice if I click the drop down I just see the nominal codes available to be used for a purchase and not the full nominal structure.
