Depending on how much you want the inner story to reflect the outer story, you might want to consider matching the Overall Story Concern or Signposts to the 3rd and 4th OS Signposts of the outer story.
For example, outer storyform Overall Story plot progression is:
Understanding - Learning - Doing - Obtaining
Inner story Overall Story plot progression is
Doing - Learning - Understanding - Obtaining
If you’re more into Journeys then your OS plot progression for the outer story is
Understanding to Learning
Learning to Doing
Doing to Obtaining
Then the OS Concern and Goal for the inner storyform is Doing.
You don’t have to do it this way, though I have found it easier and natural to connect the inner with the outer when you do it this way. The Overall Story Concerns of the first two seasons of the Tangled animated series correspond with the first two Signposts of the storyform for the entire series.
