[Freesurfer] optseq with dependent stim types in a single trial

Hello,

I am using optseq to optimize a new task. I have been playing around with the examples they have on the documentation. What I can't find is information on how to set up the trial structure when 1 trial is comprised of 3 different stimuli types: (choice 3sec --> effort (hard or easy) 3 sec --> feedback 2sec (reward or no reward)

I don't want to consider it all one long trial, because I do want to model these 3 stim types separately with jitter between each of them. So I'm not sure how to set this up within the structure of opt seq, or if it's even possible.

I also don't want to randomize the trial type itself (hard or easy) because that is the participant choice.

I'd greatly appreciate any input!

Thanks, Michelle
