Interactive Email Form data VS. CloudPages Smart Capture data

Hello. :)

I'm experimenting with the new Interactive Email Form and noticed something that puzzles me.  The Email Form requires that I set the "Field Value" which is passed to my data extension when it is submitted.  For a simple-&-not-realistic example: I'm asking what the email recipient's favourite colour is and one of my radio buttons has the label "My favourite colour is yellow" and the field value is set to "yellow".  When submitted the text "yellow" gets sent to my data extension.

However in CloudPages Smart Capture there's no "Field Value" property to set.  So when I create a fallback page for my interactive email, there's no way to have it submit "yellow", it submits the label of the radio button instead - "My favourite colour is yellow".

This seems pretty awkward to me.  Am I missing something?
