Overlapping Nav modify priority/stack/override?

Hello everyone!

This seems like a simple to be able to figure out but I can’t seem to find a setting or answer. Basic premise is that sometimes at runtime I need to overwrite a certain area of nav modify with another so that my AI doesn’t use it because it’s the shortest path from where the modifies intersect. In the image I use the purple area modify to tell the AI “don’t hope onto this one you’re on the other one”. However this pic is the cleanest it’s looked (still breaking things as the blue section is continuous) when overlaying the new modify area. Is there a setting so that the purple nav modifier is “always put on top” or “override blue modier class”?
