Returning to a step in Nurtures 2.0

Hello Sugar Club, 

From the documentation with the statement: The legacy builder allows a jump to another nurture or to a step within the current nurture. Nurture Builder 2.0 includes the Jump to Another Nurture element because jumping to a step within the current nurture is not a necessary element since the ability to return to a step is inherent in the new workflow design

My question is - with the ability to return to a step within the same Nurture - how is this done?

Kind regards

Justin
