That's right. You would have to specify at a per-event level (by specifying a flat to Rudder JSON) where to forward that event.

We have something called Transformations (user defined functions) by which you can modify the event structure from the Rudder BE. You write the transformation function (currently javascript) on our UI and that gets executed in the backend on your event stream. Using the transformation, you can also control where the event goes to. This is helpful when say you want to change the destination without pushing an update to mobile app

Got it, thanks. Is there any way of transforming old data? Lets say, I want to add a new platform to just store data about clicks, but some of these events stored thru Rudder doesn't have the element id, is there any way I can give these events a default element id before sending them off to the new platform?

Yes, that is the goal of the user transformation. You can add an element_id field while in the event before it is forwarded to destinations.

Would love to understand your use case a bit more.
