In a case specified in 11-4.2 or where costs to be collected out of the individual property of a personal representative are awarded in an action or proceeding by or against him in his representative capacity, so much of the judgment as awards a sum of money against him personally may be separately docketed and a separate execution may be issued thereupon, as if the judgment contained no award against him in his representative capacity.
