Arrays in ScreenMaker?

Does anyone know if and how you can make array type variables in ScreenMaker?

I'm trying to implement a language change feature in my GUI. No inputs from the RAPID code on the robot is involved here, so it's 100% a GUI feature.

I tried using a combobox to select a language, but from what I can tell I'm only allowed to bind an array from the RAPID code to it and I haven't been able to create an application variable of an array type either. I did find some types like RobTarget and ToolData that are arrays/structures, but they're not the regular kind of [string] array that I need.

How can I fill a combobox with an array that originates from the ScreenMaker application or a .NET extension (if neccesary)? Basically from anywhere but the RAPID code.
