Generic image target applied to multiple targets

I have 24 image targets, and I want to spawn the same generic ImageTarget for them when they are recognised, and then customize their behaviour based on scripting. How would I go about doing that?

For those interested, the AR object rendered on them is a UI showing some statistical data, where the exact values are dynamically changing and unique per marker. I don't want to maintain 24 identical copies of the exact same setup.

If there's no good way to do this, can I generate ImageTargets through scripting so I can clone them automatically?
