Diagram navigation into sub-processes then back out

I have several sub-processes that I can navigate into from one diagram. I want to know how I can have an element to navigate back to where the process started?

I have attached an image to try to describe this.

Hello mickknutson,

You can navigate to parent process diagram by clicking the diagram header (see attached pic).

Best regards,

But that just gets me back to another diagram.
How do I show the business that I want to navigate from point a to b to c and back to point a if A and C and different diagrams?

I want to coordinate the actual jump points.
What is the best practice for this?
