Trello Integration: Ability to map with the custom fields

I have several forms on Jotform that are integrated with Trello. I have them set up to create a card when completed, however, I need the jotfom fields to map to the custom fields. How do customize this?

Unfortunately, we cannot map the custom fields with our current integration with Trello. Currently, the standard fields are only supported.

Let me propose this as a new feature request to our backend team. We will keep you updated on this as soon as we receive any information from our team

Thanks.
