Repeating widget with trigger box

I have a bounding area around my level that i want to display a text widget warning the player to stop. I have it working fine when overlapping the trigger box, my problem is how to get it comes up on each overlap, but the widget wont display if it is already on screen?

I know there has to be something in blueprints that if the widget is displaying then don’t display a new one, but i can’t figure it out
