Yes, assuming you don't have any other companions, then just call and ask to guest one companion (on the same flights you are on) - best to have their PNR. They do not need to be on the same PNR. Strictly speaking, you are supposed to be in the same cabin and not further up front.
You need to watch the seat assignment from time to time as this is a manual process and if there is an aircraft change, the individual would be swept back into E-, requiring another call.
