Map Requirement Due Dates and Assignee to Trello Checklist

We currently have activity mapped to card and requirement to checklist. In Aha!, we are using due dates and assignees on our requirements. In Trello Standard or Premium, due dates and assignees are available at the checklist level, but there is no current way to map this from Aha! to Trello. We're currently having to manually update Trello due dates and assignees on requirements, and it would be ideal if these additional fields could be added within the standard integration options.
