It should be pretty easy with a plugin. It might involve adding additional runs to those zones that need it (just a suggestion).
I am in the process of writing documentation about plugin authoring. You can see what I’ve got so far at:
There will be a bare bones plugin named proto that can be used as a starting point. I will try to post it to the new plugins repository on GitHub later today.
If you give plugin writing a go, it would be helpful if you could post about what you need help with. That will help with the documentation.
