I have a feeling this would work best in conjunction with the reverse interlinears but even so one of the most used markups in my paper bible is the old "Circle to arrow" markup. (see the image).

It's not a very good example of how I would use the markup, but it demonstrates the markup.
Problem is there would need to be a way to mark "origin" and then "destination". This would definitely be a two step markup procedure.
- Highlight "not"
- Click Markup (or ctrl+k if last used)
- Highlight "Double tongued"
- Click something else or perhaps Ctrl+k to finish the markup.
- Repeat for each additional arrow destination(?).
