I am trying to create divisions in the Structure detail on the Accounts section page and I would like to be able to add contacts to each division to display who works for each division. Is there a way to add more than one contact within the Structure detail? All I can find is the ability to chose a manager.
In this case you need to create a new detail and show this detail inside organizational structure detail.
This article describes how you can setup a detail to add multiple records. Your object structure will be pretty simple: lookup column to an 'Account organizational structure' and lookup column to 'Contact' table (and base fields: CreatedOn, CreatedBy, etc.).
Then you should add this detail to a 'AccountOrganizationChartPageV2' page in the configuration.
