Right now, there is no way in flat-cam to use multiple tools for milling PCB isolation to save time. There are workarounds, but most are just that - tools following same/similar paths cutting same thing twice.
My suggestion would be an option to turn generated _CNC job preview in to a unified geometry object_. That, in essence, would make *"rest machining"* possible. We could generate G-code with bigger tools for main isolation routing, then subtract its geometry from isolation area and use small tool to finish the job thus saving machining time and tool wear.
FlatCAM already has CNC job preview, would it be possible to turn it in to a geometry object?

Someone already made this improvement for FlatCAM. Unfortunately, as with some other big improvements (like 3D acceleration for the canvas, drill path optimization), it didn't make it to the official release.
The solution for you might be to do what I do: I customize my own version of FlatCAM integrating into it things that I find useful (like above mentioned optimizations, some GCODE drill procedures that duplicate PCB-Gcode ULP from Eagle, generating negative SVG's and so on).
