Having integrated our Trello with Slack, we now face a considerable issue: there is no customization of notifications. The one available from Trello only allows either receiving all mails associated with board creation/checklist changes/etc. or not receiving them.
So, for example, when Person C opens a task for Person B, Person A will get a notification, even though they don't have to and don't need it.
With mail notifications, everything is just fine: I get notified when I am opened a task, I am addressed by someone, or when I monitor an issue. Can it be done just the same way on Slack, so that I would get only notifications related directly to me?
