NavMeshModifierVolume using an actual capsule?

I have a spherical object that I want to modify the navmesh bake, but I want it to be the area of an actual capsule shape that does the modifying as opposed to the cube shape. Is this possible? A navmesh obstacle has the option to use a capsule, although it actually ends up being a hexgonal cylinder. I imagine a sphere will increase bake time, but its the only way I can think of right now to alter my navmesh correctly...

Edit: Actually I think I've figured it out using the NavMeshmodifier script...
