This is great. Really looking forward to it. I suppose this will be available as bundle.zap in the pre_subscribe scripting API method. Is that correct? Perhaps you could also add a pre_subscription_update (with a corresponding "REST Hook Subscription Update URL") so we can have the latest zap name should it change.
