Hide external subscreen field from main program

Question

Is there a way from the main screen PBO to hide a subscreen field?

The subscreen is defined in a different Function group.

Answer 1

This is not possible: From the viewpoint of the main screen, the subscreen area is just a single element without further internal structure and cannot be examined or modified in detail. You would have to adapt the subscreen program to accept the screen modification data through some more or less generic programming interface and then perform the modification itself.
