The “super block” idea has been on our feature list for a long time but it has not been implemented, so at the moment there is no way to do exactly what you are asking for. There are two main work-arounds I can think of:
- Design each trial to contain 2 trials internally. This option obviously falls apart pretty quickly if you need to have more than 2 trials in a block.
- Have multiple protocols with the blocks in different order and select a random protocol to run for a subject
Certainly neither of these are perfect. How much do you need this feature? We’d love feedback about this so we can prioritize features for upcoming releases.
All the best,
