How to get solutions of load cases and use them with mphint2()?

Hi,
I've set up load cases in a study. After solving the model I want to use the results of each load case in mphint2(). The solution is stored in one dataset 'dset1'. There are two options for mphint2() called 'Solnum' and 'Outersolnum' to access solutions of parametric sweeps, but this doesn't seem to work with the results of load cases. So how can I access each load case result?
Best regards,
Chris
