This is a take off of the ev-od/hi-lo code.
I pulled New York eve as an example.
Keep track of your line of pairs in your history.
Select a line you want to play and add your swing number(s)
As an example The 12 and 66 line is out in the eve.
If I went with the 12__01-03-12-14-23-34 I would add my swing number(s) of choice.

Quite simple; The hard part is choosing correctly.
