When you imagine doing any subconscious task, how do you do it, currently? Like what are the steps you think about if I were to say make me a bag of popcorn?
I assume you can verbalize it?
Maybe you need to come up with stage plans the same way. A stage plan might be something like " Two on the right, three steps, left left, right. Reload. Run to port, right to left"
I use things like that on tough memory stages during the walk through utnil I'm able to memorize the stage fully. Not sure if that would work for you or not.
