I think i figured out a way to do this using the regular study import mechanism. I stripped out as much as I could from the study import files. If you kick off an import using these, it doesnt delete or import anything, then it proceeds to validate queries. I will add these files to the EHR module when I check in next. In theory we won't need this as much with 10.2; however, if something does kill the materialized datasets, we'll need some way to get them back.
