You are welcome.
Upon further review, I realize that I made this more complex than was needed.
The flow of the piece is: AB AC DE DF G AB AC DE DF
This clip implements that flow:!NoteWorthyComposerClip(2.51,Single)

from there, it is a matter of creating a visual staff with your flow instructions and to layer it with a playback staff devoid of flows and decorated bar lines. A simple copy/paste of the Special Endings and Master Repeat Close from the clip to the playback staff yields the attachment.
