In the slot mechanism, the graphics are identical for each slot.

You use the same symbol for each gate in the package. You set refds for each gate in the package to the same value, e.g. U42 or some such. You use Edit->Slot to change the slot of the gates so you have one gate each in slots 1,2,3,4.
