Hmm...What you would probably want to do, in this case, is create 3 different dkp systems, and to simply upload your snapshots 3 times, selecting each dkp system first. At least for the time being.
I could possibly implement a "mass copy" system, so you could effectively copy raid attendance from one system to another quickly. That sounds like that would accomplish exactly what you're looking for.
