Same object property differend nodes

Hi. I have a problem seems like minor but, i can't find a solution.
As you can see on the image, I have different trigger node for trigger any mission. I set a property which is name missionTriggered in the change nodes.
When a message came from PLC, missionTriggered must be false and then if the mission triggered successfully missionTriggered must be true.
So the mission doesn't triggered again and again while missionTriggered is true.
My problem is, missionTriggered that defined all changes node for all missions, acting like 1 property. But i want to define as a property to all object that coming from different messages. Let me tell clearly;
I want to manipulate the corresponding property inside all objects with a single property.
Thanks for your helps.
