In workflow 4.14, how do you use the Label Format and Description Format to display feature attributes in the Display Result Picker Activity?

I'm trying to query a service, get a feature set back and display these features in a Display Result Picker so the user can select a feature. Then from the user selected features I'm trying to do a second query on a different layer. Currently the only value displayed in the Display Result Picker is the display field attribute. I've discovered that the label/description format allows you to customize the values, but is there a way for me to customize the label/description with values from the attributes of each feature?
