Our product team uses Aha to plan our releases at the Master Feature level. Dev team leaders then "task" these Master Features out as Features and send the Features to Trello, where additional information is added by developers (and where workflow is managed). A real shortcoming of this integration is that there is no link back to the Aha feature from the Trello card. We can't map that into any of the available fields we're already using (can't map two things to the same field). Please give us a place to map this on the Trello card, or find a way to insert it automatically.
Thanks for the idea!
You can enable the custom fields power up in Trello, create a custom field in Trello, and then map that field in Aha!
Since this workaround exists, we are unlikely to implement this idea at this time. We hope you can understand.
