Hi @jreps ,

I've added a new split settings where we use an existing split (dataframe with rowId, index). I ended up making the API a bit simpler than you suggested in the issue. Does this work for your use case?

Yeah - this works and is nice and simple :). This would solve the issue if we want the same patient split within a plpData object.
