Question regarding bot jumping navmeshes

So, I want to make bots jump down a hole, think the Shotty hole on Lockout, however, the “one way jump hint” navmesh doesn’t seem to have a top or bottom adjust, only length and width, do I just angle the navmesh helper down the hole and lengthen it to bridge the 2 meshes, or is there another way to do it that works better?

Have you found a solution for this?
