Show integration indicator on feature card Merged

It would be helpful to have an overview on the feature board of which feature have been sent to Jira or other integrations. 

We only send some features through to Jira, so I would like to see which ones are sent just by looking at the board rather than clicking on each individual feature and loading it.

I imagine displaying a little dot or integration icon on the bottom of the card with a hover state showing the ids or links or something.
