Hey Tom!
Really great question - in order to leverage default values from the database, we’ll want to change up the way that we’re storing the “selected options” - since a yes/no state on a button element within a repeating group cell isn’t accessible from outside of the repeating group, I think it would be a better set up to have a custom state on the repeating group itself that stores a list of selected options.
Here’s a video walkthrough for you: https://www.loom.com/share/ff1a16a9e29e4107a16f9da5607ce18d
Let me know if you have any questions!
