Only one thread in batch model

Hello guys.

My situation is the following, I am using a bacth model to test 6 UUTs, in one of my initial steps I am using a VI as a pop up to select some input chanels for thermocouple measurements, I want the user to select the chanels that have been connected to the analog board,  but since I am using batch model, the pop up VI shows up 6 different times (or the number of test sockets), but I don't want it, I just want to the VI/step to execute only in one thread but I want the output values are available in all the test sockets, is there a way to do that?

Thanks for your comments
