How can I extract button values from an HTML attribute and use those values in recommendation rules

Summary

Would like to start making nicer HTML attributes with JET UI elements in it and extracting the values to drive other CPQ attributes

My company is in love with all of the fun and glorious items they're finding in the Oracle JET Developer's Cookbook.  Problem is that there's no obvious way to incorporate these into CPQ (on the configuration side).

Perfect example here...the cookbook shows how to add a push button.  Great.  How do I get this into CPQ?  How do I use the value from the button?
