Selecting one of multiple stimulus lists

I can’t seem to work around this problem (possibly the solution involves conditional macros?)

I’m on SuperLab 4.5 and I have eight different audio stimulus lists (each containing 40 files) but I want the experiment to only present one of them to the participant. Each new participant should get a different stimulus list.

Is this possible? What’s the easiest way?

I suggest using SuperLab’s Participant Groups feature, which is found under the Experiment menu. If you have separate sets of lists segregated into different blocks, then Participant Groups will let you restrict which blocks run per group.
