DeltaV Live script for open a display

Hello everyone, hope you all are fine.

So, I want to use a ComboBox on DeltaV Live to be able to chose wich process is gonna run. As a process interlock, when a process is running this ComboBox is not avaible anymore for new choices.

The problem is that when I change the display and come back to the same display, the ComboBox resets to its default value and, by script, it changes back the "default process" at the screen, which is not the one running and the ComboBox to select the process still locked due another process is running.

My question, is it possible to make a script to run when the display opens to change this ComboBox default value to the one running? As far as I know I can only run a script when a contextual display goes on/off or with some screen change, but this is not a good solution for production or if there is a better way to do this.

Thanks in advance!
