Hi Laura,

Thanks for confirming. Study datasets out of the box would not be able to support something like this.

If you have development resources, you could build your own module with a custom schema and tables that could utilize a combination of a primary key and unique constraints to accomplish what you need out of these tables, but these would technically not be study datasets since they would be living outside of the study schema.
