Accessing List Variable Descriptors in a Text field?

I have created a Global List Variable. In doing so, I used the ## notation to create "descriptions" for the entries. This is great and I see them when I tap on the variable item line.

But I want to put the description in a text field in my wallpaper's UI. I cannot seem to do this. I can put in the global variable's value with ease.

How can I access the descriptor for the global variable's current value?
