Hello, I'm inside an activity and I want change to a specific stage. For that, i use the Call pxChangeStage but the parameters ChangeToStage take only a raw String and I can't specify a property. When use a property an error appear and say invalide stage.  So I've copy paste pxChangeStage to a CustomPxChangeStage and change the parameters ChangeToStage from "IN" to "OUT". With that it works : i can put a property and it is well executed. Is-it possible to update Call pxChangeStage and let us the possibility to use a property instead of this tricks ?
