Execution order of customisations

Hello - I have a situation where 2 different customisations are overriding the same method. In this case it is the ConfirmShipment method of the SOShipmentEntry graph. Like so...

public class SOShipmentEntryExt : PXGraphExtension<SOShipmentEntry>
{
  public delegate void ConfirmShipmentDelegate(SOOrderEntry docgraph, SOShipment shiporder);
  [PXOverride]
  public void ConfirmShipment(SOOrderEntry docgraph, SOShipment shipment, ConfirmShipmentDelegate baseMethod)
  {
    //do some work
  }
}

Is there a way to control which customisation performs it’s actions first?
