How to not isolate the board edge when footprints intersect?

[jephthai]

I found this discussion about how to make FlatCAM not route the outside edge of the board. This works, as long as the outside edge toolpaths fully enclose the board:

But suppose some footprints extend to the board edge, such as these SMA connectors:

If I delete the enclosing toolpaths, I end up losing isolation routing toolpaths in the board interior. I have not been able to find a way around this, thus far, and am curious if there might be a solution that's just not obvious to me somehow.

Thanks!
