single puzzle to call a JS function w/arguments and accept a return value?

Soft8soft Team,
Is there a single puzzle that would allow me to call a JavaScript function with arguments and accept a return value? We currently have a puzzle that will call and pass arguments to a function in the external interface. We have a separate puzzle that will accept a call and arguments from a function in the external interface. I use both of these together when I need to call JavaScript from the puzzles and receive a return value. It is not an elegant way to write code. In my opinion, it would be convenient if we had a single puzzle that could call a function and receive a return value. This puzzle would be like the “call JS function” but it would be an output style block rather than a previous-next style block. I Photoshopped an image to explain what I am trying to describe. This block would not replace the current “call JS function” puzzle. What do you think?
Thanks!
