Client Level (MCC) Conversion Tracking
Have an option to create a conversion tracking code on client level, the same way as MCC level conversion tracking code in Google.
This is on our backlog

With the release of Universal Event Tracking (UET) which replaces the current conversion tracking mechanism, you only need to create a tracking code at the customer level which can be used across all your campaigns and accounts. You can learn more about UET at http://bingads.com/uet.
