Hide/Show section based on a subform entry

Hide/Show section based on a subform entry

Hello Creator community,

Question - can I hide/show a section based on whether or not a value exists within a subform?

Example: 
A subform contains a picklist called "Tax Forms". If an item is added to the subform with a "W-2" in the "Tax Forms" field, can it then show a section elsewhere in the app called "Additional W-2 info"?

Where I'm at:
Here is the screen I would normally add the workflow to hide/show a section. But the "Select a field" drop-down doesn't allow me to set the condition to a value on a subform. So I'm hoping it can be done via deluge code. Perhaps a loop that iterates through all subform entries to see if there is a match or not. 


Thanks in advance,
