Hi Yuting,
I'm Maho, a member of the researcher experience team. Can I ask what the structure of Block A and B looks like and why you want to separate them, especially if you want to pull items from the same pool for the two blocks? If you can do with one block, you can add "stimulus_pattern": {"order": "random", "limit": 12} to your trial template in order to randomly pull 12 items from the pool for each participant. If you need to have two blocks and you don't want the items in the blocks to overlap, you can also split the 36 items into two sets, one for Block A and the other for Block B, and add "stimulus_pattern": {"order": "random", "limit": 6} for each.
Please let us know if you have any follow-up questions.
Best,
Maho
