Multiple image targets displaying the same content

Our use case is this:

We have an x number of calling cards, each identical in design but with different text on them (personalia for different people)

Each calling card will be added to the media library as a tracking image. On the basis of a url / query parameter, we will enable one tracking image only using this is a reference:

https://docs.zap.works/studio/scripting/reference/targetfinder/

No problems thus far. Now, when the appropriate image is detected, content we have defined in studio should be displayed on and tracked by that specific tracking instance. Is there a way of saying in a script; take all content that is child to this root and update its position and perspective on the basis of this images tracking events.

I suppose I am looking for a concept similar to what prefabs are in Unity. If not, what would be a sensible workflow for displaying the same content on multiple images, without having to define and maintain it in duplicate.
