show hide field on document upload popup

[llarge]

Hello, I'm using the call RPG behavior with the file upload field. I want to try and hide and show an extra field based on one of the field values in the popup. I'm pretty sure I could do this if I convert that popup to a form but I was wondering if there would be a way to do it without having to create an extra widget. Right now it looks like this.

I would love to only show the checkbox if the division is a specific value. Is this something that can be done now or possible a new feature?

There should already be a "Depending On App Var = true" associated with each prompt field. So I think you should be able to already do this today.
