I see what you’ve done there. You’ve captured the concept that print is presenting.
Nemeth Code does not provide rules for this sort of cancellation/borrowing combo. As you’ve discovered and utilized, it does provide tools for multiple cancellations and even multiple levels of cancellation.
If you do as you’ve suggested in your attachment, using cancellation and replacement where print carries “backwards,” you must make the change abundantly clear in a transcriber’s note.
Thank you for the question!
