Multi-step form not saving hidden fields on Create New Thing

I’m building a multi-step form, changing steps using state changes. When I get to the final step which saves/creates new thing, the form fields in the previous steps are not passing the data to the database.

I’ve seen some topics about using auto-bind, but I would like to not create half empty rows (only for users to never complete them). Is there a way to have a single workflow (Create New Thing) work with a multi-step form?

Thanks.

Can save the form values into custom states, before they get hidden. Potentially group similar types into lists, so long as you’re careful with possible duplicates.
