Unfortunately there’s no straightforward way to do that in PCIbex, as it would require keeping track of information across runs. The only thing close to that is the internal counter, which increases with each new submission, and which can be used to automatically assign different groups to participants, but it doesn’t keep track of every single participant specifically
You would need to set up your own solution to keep track of each participant’s submissions and communicate with your PCIbex experiment to run the desired set of stimuli. I have never tried to do something like that before, but it surely isn’t a trivial task. I’m happy to answer any questions though
