skip to a specific block

My experiment contains multiple blocks, each containing different orders of an auditory task, a click-on-the-dot task, and a visual search/object identification task. It appears as a "tri-task" to the participant. When performance falls below a certain level on the visual search task, I want to jump to a "dual task" block, then jump back to the tri-task after a given amount of time. I can end a task based on the performance criteria, but can't figure out how to jump to specific blocks.

I also have this task coded using separate blocks for the auditory, dot, and visual search tasks, instead of 1 long script including all 3 tasks, in case that organization is more amenable to a "skip to block" process.

Suggestions?

Thank you! PsyToolKit is an excellent tool!
