Subscribing to build events for a configuration results in a lot of notifications for e.g. daily builds. If you could add a tag to the notification it would be possible to limit the notification to e.g. QA builds or whatever builds you are interested in. Would be helpful to notify those not interested in every single build.
Thanks for this request. We were recently discussing adding conditions to notification subscriptions. It’s not an immediate priority, but it is definitely on our to-do list.
